Earthquake Risk, Insurance, and Recovery: Issues for Congress 
 
Summary 
This report examines earthquake catastrophe risk and insurance in the United States in light of 
recent developments, particularly the devastating earthquakes in Haiti and Chile. It examines both 
traditional and non-traditional approaches for financing recovery from earthquake losses as well 
as challenges in financing catastrophe losses with insurance. The report explores the feasibility of 
a federal residential earthquake insurance mechanism and assesses policy implications of such a 
program. 
So far in the 111th Congress, six bills have been introduced that would broaden the federal 
government’s role in insuring, mitigating, and financing recovery from natural catastrophes. 
Proposals include (1) establishing a national consortium to allow states to aggregate risk from 
state-sponsored insurance pools and transfer such risks to the capital markets through catastrophe 
bonds (H.R. 2555/S. 505), (2) a provision for a tax-free accumulation of reserves to pay 
catastrophe losses (H.R. 998/S. 1486), (3) a Treasury program to guarantee state-issued debt 
(H.R. 4014/S. 886), (4) a federal reinsurance backstop (H.R. 83), (5) a provision to establish 
individual catastrophe savings accounts (S. 1484), and (6) establishing a bipartisan commission to 
examine catastrophe risks and make recommendations for the management and financing of such 
risks (S. 1487). On March 10, 2010, the House Subcommittee on Housing and Community 
Opportunity and Subcommittee on Capital Markets, Insurance, and Government Sponsored 
Enterprises held a joint hearing on H.R. 2555. A mark up on H.R. 2555 is expected in April 
2010.This report will be updated as events warrant.

Earthquake Risk, Insurance, and Recovery: Issues for Congress 
 
his report examines earthquake catastrophe risk and insurance in the United States in light 
of recent developments, particularly the devastating earthquakes in Haiti and Chile. It 
T examines both traditional and non-traditional approaches for financing recovery from 
earthquake losses as well as challenges in financing catastrophe losses with insurance. The report 
explores the feasibility of a federal residential earthquake insurance mechanism, and assesses 
policy implications of such a program. 
Recent Developments 
On January 12, 2010, a magnitude 7.0 earthquake struck near Port-au-Prince, Haiti, causing 
widespread economic losses from property damage—the worst in the Caribbean region in more 
than 200 years. Aftershocks were felt in the Dominican Republic, Cuba, and Jamaica, though 
little to no damage occurred outside of Haiti. While smaller earthquakes are relatively common, 
the last major earthquake to affect Haiti was in 1842.1 The Haiti earthquake occurred along the 
Enriquillo Fault Zone, which runs east-west along Haiti’s southwest peninsula. The islands that 
form the Lesser Antilles and Greater Antilles outline the contact zone between the Caribbean and 
North American plates. According to the USGS, this region is seismically active due to the 
relative motion between the plates, and the Haiti earthquake has generated many aftershocks that 
will likely continue for months. The potential for future earthquakes in the surrounding regions 
appears to be high, according to the USGS. Earthquakes greater than magnitude 7 have occurred 
in Puerto Rico, Jamaica, Dominican Republic, Martinique, and Guadeloupe over the last century.2 
The United States Geological Survey (USGS) reported that the geological fault that caused the 
Haiti earthquake is part of a seismically active zone between the North American and Caribbean 
tectonic plates.3 The proximity of the Haiti earthquake to the New Madrid Seismic Zone (NMSZ) 
in the Central United States, and a number of major U.S. population centers with a high level of 
economic development, has reminded U.S. policymakers about the earthquake threat to the 
interior of the continental United States and the need to have contingency plans in the event of a 
mega-catastrophic earthquake.4 A mega-catastrophe is defined as a catastrophic event that causes 
losses so large and unpredictable that private insurers either resist offering coverage or charge 
premiums so high that significant numbers of customers do not want or cannot afford the 
insurance. 
Reinsurance broker Holborn Corp. has estimated economic damage to property values in Haiti to 
be over $10 billion. Because of the country’s low income rates and limited insurance penetration, 
insured losses are expected to be a fraction of economic losses, perhaps in the low-single-digit 
billions of dollars.5 The Haiti government received an $8 million payment from the Caribbean 
                                                
1 Two large earthquakes in the middle of the 18th century occurred close to Port-au-Prince, likely along the same fault 
line, and caused widespread devastation. These occurred in 1751 and 1770 and both had an estimated magnitude of 7.5.

Francisco earthquake (a 7.7 magnitude quake which killed about 3,000 people) and the 1886 Charleston, SC, quake (a 
7.3 quake that killed about 100 people), according to the USGS.

amount to less than $20 million annually. See http://www.claimsmag.com/News/2010/1/Pages/Haiti-Lacks-Insurance-

Earthquake Risk, Insurance, and Recovery: Issues for Congress 
 
Catastrophe Risk Insurance Facility (CCRIF) as a result of insured losses from the recent 
earthquake. The funds will serve as a revenue stream for the government to continue operating 
after the earthquake. CCRIF is a risk-pooling facility owned, operated, and registered by 16 
Caribbean governments in partnership with the World Bank and established to provide economic 
stability for the catastrophe-prone region. CCRIF allows Caribbean countries to pool catastrophic 
risks, reduces the cost of insurance, and provides Caribbean governments with short-term 
liquidity when the policy is triggered after a major hurricane or earthquake. The recent earthquake 
was of sufficient magnitude to trigger the full policy limit for the earthquake coverage, effecting 
payment after a 14-day waiting period.  
Researchers at the USGS, insurance market experts, and computer modeling companies agree that 
the potential cost of earthquakes continues to grow due to increasing urbanization in seismically 
active areas and the vulnerability of older buildings that have not been upgraded to meet current 
building codes. The most recent earthquakes in the United States have been of relatively low 
magnitude and did not result in major losses. On February 10, 2010, the USGS reported that a 3.8 
magnitude earthquake hit about 50 miles northwest of Chicago with ground shaking felt as far as 
Wisconsin, Iowa, and Indiana. There were no reports of injuries or damage. In December 2009, 
four small quakes with a 3.1 magnitude were felt in Arkansas, Missouri, Tennessee, and Kentucky 
without any economic damages reported. Three months earlier, on September 30, 2009, an 8.0 
magnitude underwater earthquake struck 125 miles from the U.S. territory of American Samoa. 
Again, there were no reported economic damages. 
The 2008 National Seismic Hazard Maps by the USGS have changed the perception of 
earthquake risk in the United States.6 Catastrophe modeling firms have updated their models with 
research from the latest maps, bringing potentially significant implications for how insurers and 
reinsurers manage, underwrite, and price U.S. earthquake risk. Since a 6.7 earthquake shook the 
Northridge areas of southern California on January 17, 1994, claiming 60 lives, injuring over 
7,000, and leaving 20,000 homeless, Americans have not experienced another major quake in 
terms of lost lives and property damages.  
A major earthquake could still have catastrophic impact on insurance companies and the insured, 
impose significant costs on the U.S. economy, and disrupt U.S. financial markets. Although 
individual insurance companies could face massive losses from a major earthquake, the industry 
as a whole is not likely to become insolvent for two reasons. First, U.S. earthquake construction 
standards are higher than Haiti’s, so the damages would presumably not be as extensive. Second, 
there is generally a low purchase rate for earthquake insurance. The relative lack of earthquake 
coverage is thought to be due to costly premiums, large deductibles, and limited availability of 
coverage, resulting in reliance on government disaster relief in the event of a mega-catastrophe.  
Financing economic recovery after a major earthquake is likely to be costly and require both 
private and public recovery funds. Currently, money to finance disaster recovery comes from 
state and federal disaster aid, private and public insurance, private loans, contingent financing, 
and personal savings. Insurance is arguably the most efficient form of pre-disaster risk financing 
to mitigate losses and reduce the financial vulnerability of property owners and governments to 
earthquake risk exposure.

Earthquake Risk, Insurance, and Recovery: Issues for Congress 
 
Since the late 1990s, capital markets have entered the reinsurance business through the provision 
of alternative risk transfer (ART) and financing instruments that provide excess of loss coverage 
at the highest loss levels. ART allows domestic insurers to leverage retained capital to help 
increase insurance loss capacity and reduce their sensitivity to extreme events. Catastrophe bonds, 
for example, currently offer insurers and reinsurers an innovative approach to financing disaster 
risks by transferring some of the catastrophe risk to global financial markets.  
The vast majority of businesses and individuals in seismic zones do not purchase earthquake 
insurance, preferring to take their chances rather than pay for protection at the cost that may be 
considered too expensive for such a remote event. As a result, the government, through taxpayer-
financed federal disaster assistance for disaster victim compensation, has become the de facto 
insurer of last resort and source of financial protection after a disaster occurs.  
In the 111th Congress, several earthquake catastrophe risk and insurance issues could arise, 
including (1) revisiting the nature and extent of earthquake and tsunami hazards in the United 
States and (2) addressing the challenges of financing recovery given limited capacity of national 
financial markets to absorb the cost and economic burden of a devastating mega-earthquake. 
Policymakers are concerned about finding ways to reduce society’s disaster risk to help 
homeowners, insurance companies, financial firms, and federal and state governments reduce 
future losses from natural hazards. Members of Congress have begun to explore alternative policy 
designs and to consider helping the private sector pre-fund and diversify disaster risk by financing 
catastrophic losses through insurance, reinsurance, and capital from financial institutions and the 
investment community. These approaches are discussed below. 
Basics of Residential Earthquake Insurance 
Many people assume their residential insurance policy fully protects them, but most standard 
homeowners’, mobile-home owners’, condominium, and renters’ insurance policies do not cover 
earthquake damage. The Appendix illustrates the earthquake hazard exclusion language in 
standard homeowners’ policies. Earthquake coverage must be purchased as an endorsement to an 
existing homeowner’s or business owner’s policy or as a separate policy. It includes coverage for 
damage to the building structure, contents or personal property, and loss of use of the structure. In 
the case of commercial business the policy covers loss of business income. Vehicles are covered 
for earthquake damage by the comprehensive insurance policy of an automobile policy. 
In general, consumers typically experience multiple challenges concerning residential earthquake 
insurance offerings, including the following: 
•  policy premiums that viewed as unreasonably expensive; 
•  deductibles that are 15% of the amount of the policy (not the loss); 
•  lack of knowledge that earthquake coverage is available or misinformation 
concerning the terms of such insurance; and 
•  lack of adequate incentive to take preventive action to reduce shaking losses, fire 
losses, and injuries.  
California is the only state that requires insurers that sell residential property insurance to offer 
earthquake coverage to their policyholders. After the earthquake in Northridge, California, in 
1994, most insurers either stopped selling new homeowners’ insurance policies or greatly

restricted the sales of such policies. In 1995, as a result of insurers’ reluctance to offer earthquake 
insurance because of the fear of insolvency, the California state legislature created a privately 
financed, publicly managed organization—the California Earthquake Authority (CEA)—to offer 
primary coverage for property losses arising from a seismic event. In offering earthquake 
coverage, insurance companies can become a member of the CEA and offer the CEA’s residential 
earthquake policies, or they can manage the risk themselves. To date, companies that sell over 
two-thirds of the residential property insurance in the state have opted to become CEA 
participating companies. The CEA began providing residential earthquake insurance in December 
1996 with a $10.5 billion funding package.  
U.S. Exposure to Earthquake Risk 
Calculating earthquake risk levels depends upon proximity to earthquake faults, the age and type 
of dwellings, and the soil types near those dwellings. Some parts of the country that have not 
experienced earthquakes for 200 years or more might be more susceptible to earthquakes than 
areas that have experienced recent earthquakes. The reason is that earthquake faults build up 
tension over long periods of time, which become earthquakes when that tension is suddenly 
released. It is theorized that relatively recent earthquake activity means that faults have released 
built-up tension—a lack of earthquake activity can mean that tension is still building and could be 
released at any time as an earthquake. 
Table 1 shows that on average over 3,000 earthquakes strike the United States each year. Based 
on insured loss data provided by the Insurance Services Office, a relatively few earthquakes cause 
disastrous accumulation of economic losses because most occur in sparsely populated areas. Most 
Americans live in areas considered “seismically active,” although the degree of vulnerability to 
earthquake risk varies greatly. The size and geographical location of the quake, and to some 
extent its timing, determine the magnitude of economic losses from property damages. According 
to the A.M. Best Company, an insurance-rate-making company based in Newark, New Jersey, 
earthquakes have caused insured property losses in every U.S. state during the past 100 years, but 
potentially damaging earthquakes are more likely to occur along the Pacific coast, the Mississippi 
valley around New Madrid in Missouri, Alaska, Utah, South Carolina, and the New England 
region around Boston.7  
Table 2 shows the estimated impact of historical U.S. earthquakes if they were to happen today. 
On August 6, 2009, AIR Worldwide and Risk Management Systems (RMS) announced releases 
of new earthquake models for North America.8 The new model versions, based partly on the 2008 
USGS National Seismic Hazard Maps, produce significantly reduced loss estimates for most 
regions of the United States. While the amount of reduction varies by model, by region, and by 
type of business, most companies with significant earthquake exposure saw large reductions in 
their model loss estimates. Implemented as is, these changes will affect company risk 
management decisions, including earthquake underwriting, pricing, and reinsurance purchasing.

Financing Recovery from Earthquake Losses 
At present, funds to finance earthquake recovery come from several sources: state and federal 
disaster aid, insurance, private loans, personal savings, and structured finance securitization. 
Insurance is the most common form of financing of recovery from catastrophic disasters, such as 
earthquakes and hurricanes. While it is widely agreed among disaster policy experts that 
Congressional Research Service 
5 
Earthquake Risk, Insurance, and Recovery: Issues for Congress 
 
insurance by itself would not mitigate losses from seismic hazards, when combined with options 
such as structural and non-structural mitigation, building codes, and land-use planning, insurance 
could be used as a financial incentive for action designed to help reduce losses from future 
earthquakes. 
Insurance involves the collection of premium from pool participants before an event occurs so 
that a source for payouts is available to compensate victims following a disaster. Insurance pools 
typically purchase reinsurance to diversify catastrophe risk, expand the capacity of the pool to 
cover risks, and hedge against the possibility of bankruptcy from catastrophic risks. Insurance 
also provides other benefits beyond post-event compensation, namely property loss mitigation. 
Commercial insurance may be viewed as a risk-financing tool used to accumulate funds in 
preparation for future earthquake disasters, diversify risk among the international capital markets, 
and reduce the direct impact of disasters on property owners. As a risk-transfer strategy, insurance 
may also be used to help minimize catastrophe losses, reduce the government’s exposure to post-
disaster payouts, and provide a safety net for property owners and communities affected by 
natural disasters, such as earthquakes. 
A brief review of the financial capacity of the U.S. property and casualty insurance and 
reinsurance industry reveals that the insurance industry’s capacity to handle large catastrophic 
losses may be substantially less than aggregate figures suggests. A repeat of the 1906 San 
Francisco earthquake could cost insurers almost $100 billion in insured property damages. 
According to the Insurance Information Institute, the policyholders’ surplus of the entire property 
and casualty insurance industry was $490.8 billion as of September 30, 2009.9 Policyholders’ 
surplus is defined as the “net worth” or “owners’ equity” of a firm. It is a measure of the capacity 
of insurers to underwrite policies, and it must increase to meet the demands of a growing U.S. 
economy and claims from hurricanes and other natural hazards. Only a fraction of this industry-
wide total surplus amount (e.g., approximately 20%) would be available to compensate victims of 
a major earthquake. Furthermore, insurers must rely on this same portion of total surplus to pay 
for other potentially catastrophic and unpredictable risks.  
Challenges in Financing Earthquake Loss 
The 111th Congress may choose to assess whether existing sources of funding of catastrophe 
losses will be adequate to finance recovery from a mega-catastrophe earthquake. In the aftermath 
of mounting natural disaster losses over the last two decades, property and casualty insurers have 
sought to limit their exposure to catastrophe risk while simultaneously exploring new and 
innovative sources of capital aimed at financing catastrophe losses. Although insurers are skilled 
at handling high-frequency, low-severity “non-catastrophic” events, like auto and home losses, 
that follow a predictable claims frequency and magnitude, they face substantially greater 
difficulty when attempting to price and insure low-occurrence-probability, high-consequence (LP-
HC) risk. Furthermore, there is a finite amount of protection (capacity) that the insurance industry 
can offer to finance a mega-catastrophic earthquake. The amount of catastrophe insurance 
coverage is limited by the potential magnitude of possible insured losses, the sporadic and 
unpredictable nature of earthquakes, and ability to accurately estimate future losses and price 
coverage. Moreover, existing regulatory and accounting systems also result in catastrophe

reserves being taxed as profits, discouraging insurers from accumulating loss reserves for 
catastrophes. Current tax laws discourage establishment of a reserve for a loss that has not 
occurred. 
The amount of catastrophic insurance is limited by  
•  actuarial and rate-setting difficulties; 
•  industry capacity to meet the payout requirements resulting from a mega-
catastrophic earthquake; 
•  difficulties in determining both the insurability of properties and the damages 
resulting from earthquakes; 
•  adverse selection and risk-spreading difficulties, including those associated with 
reinsurance; 
•  accounting and Internal Revenue Service constraints on the build-up of insurance 
company catastrophe loss reserves; and 
•  ineffectiveness of current loss-reducing activities (building-code enforcement and 
land-use zoning). 
A general discussion of these interrelated challenges follows. 
Actuarial and Rate-Setting Difficulties 
One set of challenges facing private insurers involves actuarial and rate-setting difficulties that 
stem from the lack of sufficient data on past losses to estimate the chance of future losses and the 
potential for catastrophic losses that can jeopardize insurers’ financial stability. Estimating future 
losses is difficult because earthquakes occur infrequently and at any location, and the magnitude 
of losses is highly uncertain. Insurers must instead predict losses from technical studies and 
computer simulation models, which may arguably be less reliable than actual prior historical loss 
data.  
Insurers would need to set a premium for each potential customer or class of customers in order 
to generate enough revenue to cover both the expected loss and earn a profit. Insurers must be 
able to estimate the frequency of specific events occurring and the magnitude of the loss should 
the event occur, a condition limited by the low-probability/high-consequence nature of 
earthquake risk and the difficulty in identifying what losses may occur. Insurance companies risk 
insolvency or being uncompetitive by underpricing or overpricing, respectively. 
Adverse Selection and Risk Spreading 
Insurers also face adverse selection and risk-spreading difficulties, including access to adequate 
reinsurance for earthquake peril. The problem is that risk is not sufficiently spread over a larger 
geographical area including areas which are relatively unlikely to suffer a catastrophic 
earthquake. Traditional insurance principles for insurability require that there is sufficient demand 
to yield appropriate levels of income revenue for insurers to supply the coverage. There is a 
tendency for mostly high-risk consumers to purchase policies. This results in a poor spread of risk 
and an inadequate premium base. Economists note that this “adverse selection” problem in 
insurance markets generally persists for two reasons: (1) the insured possess information on their 
Congressional Research Service 
7

particular risk, which is unknown to the insurer; and (2) consumers have short time horizons in 
determining the expected benefits relative to the up-front costs (rates and deductibles), or 
compare costs with potential benefits and conclude that loss-reduction measures are not good 
investments. Insurers may attempt to address or correct this asymmetrical information problem by 
creating different risk categories with corresponding price differences to discourage high-risk 
consumers from purchasing the low-premium policy.  
Tax, Accounting, and Regulatory Constraints 
Another set of challenges to financing catastrophe risks involve tax policy and regulatory 
constraints on the build-up of insurance company catastrophe loss reserves and the industry’s 
ability to raise external capital during times of financial crisis. Under current federal income tax 
provisions, premiums collected by insurers and placed in a reserve fund for catastrophes are 
treated as excess profits and taxed at the corporate income tax rate. Insurers view this as a major 
impediment to marketing of earthquake insurance, and they have supported a longer loss carry-
forward period or tax-free reserves for potential earthquake losses.10 Insurers might consider 
offering insurance coverage at a price level high enough to cover the high-end in the range of 
expected losses. The rate, however, would be so high that it may not be marketable or regulators 
may not approve extremely high catastrophe rates. At this point, insurers typically have opted to 
withdraw from lines of insurance in catastrophe-prone areas.  
Low Insurance Participation  
A high percentage of property owners in areas prone to earthquakes simply do not have 
earthquake insurance, relying instead on good fortune or federal emergency disaster relief 
assistance to cover uninsured losses. Researchers have found that Americans are reluctant to 
purchase earthquake insurance because of the high cost of insurance and low likelihood of a 
disaster.11 Moreover, earthquake insurance is not required as a condition for federally secured 
mortgages, as is currently the case of flood insurance in federally designated flood zones. Fannie 
Mae and Freddie Mac require homeowners with federally backed mortgages to buy insurance for 
flood and windstorm damage, but not for earthquakes. Fannie and Freddie have dramatically 
changed the landscape for homeowners’ property insurance by not requiring coverage for 
earthquakes. The penetration of earthquake insurance has been low, and the government, through 
disaster relief assistance, continues to serve as the predominant bearer of earthquake catastrophe 
risk. 
The lack of insurance or underinsurance against earthquakes could negatively impact bond and 
equity markets, the mortgage loan industry, and government budgets at all level. With roughly 
12% to 15% of exposed mortgaged properties covered by earthquake insurance nationwide, a 
mega-catastrophe could leave a number of mortgages in default with lack of sufficient underlying

agencies, uninsured losses are absorbed by those agencies, a situation that could create a strain on

the U.S. financial system and do little to help the owners of the distressed properties. In addition, 
federal, state, and local governments would likely be called upon to expend funds in emergency 
response and recovery at the same time as they lose tax revenues. Meanwhile, federal 
policymakers have focused on finding ways to enhance the private sector’s ability to spread risk. 
Is Federal Earthquake Insurance Feasible?  
As stated earlier, a basic principle of insurance is the reduction of overall risk by pooling or 
spreading individual, independent risks. Insurance companies typically price risks where the 
frequency and severity of potential claims are limited, estimable, and stable. This principle and 
insurance practice tends not to hold when a single event affects many insureds simultaneously, as 
in the case of a major earthquake. In the event of uninsured losses, the federal government has 
become the de facto bearer of the cost of repairing or reconstruction of buildings damaged by 
catastrophic earthquakes. Another option, however, may be to create a national catastrophe fund 
(federal residential earthquake insurance program) to ensure adequate capacity and solvency of 
the insurance industry to meet consumer demand for protection against earthquake risks, which 
could minimize federal outlays for uninsured losses.  
An explicit government insurance program could have several advantages: limited bankruptcy 
risk, the ability of the government to spread risk over time, financing of short-run losses by 
borrowing, and lower requirements for federal disaster relief. The disadvantages would be the 
potential burden on taxpayers, weak underwriting incentives to keep the cost of claims low, 
preemption of existing and future private sector capacity, difficulty in implementing or sustaining 
risk-based pricing in a political environment, and potential impediments to capital market 
innovations, such as catastrophe bonds and options, that securitize catastrophe risk. 
Since the late 1960s, the prevailing thinking among federal and state legislators and regulators 
has been that earthquake risks could be managed and financed in the private sector. Congress 
explicitly chose not to implement a federal earthquake insurance program because the 
justification that the earthquake hazards could not be insured by the private sector had not been 
convincingly made.12 Policy debate during and after the 88th Congress following the 1964 
earthquake and accompanying tsunami at Alaska’s Prince William Sound led to the creation in 
1968 of the National Flood Insurance Program (NFIP).13 Congress, however, waited several years 
before addressing the nation’s exposure to earthquake hazards with the creation of the National 
Earthquake Hazards Reduction Program (NEHRP) in 1977.14 NEHRP established for the first 
                                                
12 See letter of transmittal accompanying the Federal Insurance Administration report issued pursuant to Section V of 
the Southeast Hurricane Disaster Relief Act of 1965 from George K. Bernstein, Federal Insurance Administrator, to 
Honorable George W. Rommey, Secretary of Housing and Urban Development, dated November 23, 1971. The letter 
was included as the foreword to the report. 
13 The National Flood Insurance Program was established under the National Flood Insurance Act of 1968 (P.L. 90-
448, title XIII, § 1360, August 1, 1968, 82 Stat. 476, codified at 42 U.S.C. §§ 4001-4128). 
14 The NEHRP was established by the Earthquake Hazard Reduction Act of 1977 (P.L. 95-124; 91 Stat. 1098; Oct. 7, 
1977). The NEHRP consists of four agencies: Federal Emergency Management Agency (FEMA); National Institute of 
Standards and Technology (NIST); National Science Foundation (NSF); and United States Geological Survey (USGS). 
The goals of NEHRP are to (1) reduce earthquake losses, (2) improve techniques to reduce seismic vulnerability of 
facilities and systems, (3) improve seismic hazards identification and risk-assessment methods and their use, and (4) 
improve the understanding of earthquakes and their effects.

time a federal policy to encourage research on and implementation of methods to reduce 
earthquake losses.  
Substantial progress has been made in the fields of earthquake science and engineering following 
the implementation of NEHRP, particularly with respect to seismic hazard identification and 
strategies to reduce seismic vulnerability of facilities and systems through land use practices and 
improvements in design and construction techniques. Disaster policy experts agree that despite 
the effort of four federal agencies that collaborate under the NEHRP, one issue that has not been 
adequately addressed is the economic consequences of a catastrophic earthquake, and the 
efficiency and adequacy of present mechanisms for financing catastrophic earthquake recovery. 
NEHRP was not required to address this issue.  
Policy Issues and Questions 
The 111th Congress is likely to face the following key policy questions with respect to earthquake 
risk, insurance, and recovery:  
•  Is earthquake risk uninsurable in the private market?  
•  Is a federal residential earthquake insurance program feasible?  
•  What are the costs and benefits of government intervention in the catastrophe insurance 
market?  
•  Do benefits outweigh costs to taxpayers for providing a financial backstop for the 
insurance industry?  
•  Should federal earthquake insurance be compulsory, and, if so, what would be 
the enforcement mechanism?  
•  What should be the role of land-use regulations and building codes? Is current 
insurance regulation conducive to creating private sector incentives for 
mitigation?  
In broadening this discussion beyond earthquake insurance to catastrophe risks insurance in 
general, insurance market experts recognize that the risk of a mega-catastrophic event could pose 
a significant capacity and liquidity problem for insurers who receive relatively stable premium 
flows but suddenly need large amounts of cash to cover disaster losses. A sudden loss of 
policyholder surplus, which is the statutory net worth or cushion available to insurers for handling 
the unexpected, could have an adverse effect on the financial strength of the property and casualty 
insurance industry. To better manage catastrophic risk, insurers have sought to raise premiums, 
impose a percentage deductible, and reduce the amount of concentration of their exposures. These 
changes have led to availability and affordability problems for many homeowners in disaster-
prone areas.  
Finally, various government actions, such as access to federal disaster assistance or insurance, are 
likely to affect the behavior of individuals and firms in responding to catastrophe risk. By making 
disaster-prone areas safer through a federal earthquake insurance scheme, however, government 
policy could have the unintended consequence of creating incentives for people to move into 
harms way, which would increase the potential for catastrophic property damages and economic

losses. Hence, Congress will find no shortage of issues to debate and resolve when considering 
proposals to establish a federal earthquake insurance program. 
Legislation  
So far in the 111th Congress, six legislative approaches have been introduced that would broaden 
the federal government’s role in insuring, mitigating, and financing recovery from natural 
catastrophes in the United States. Proposals include the following: (1) establishing a national 
consortium to allow states to aggregate risk from state-sponsored insurance pools and transfer 
such risks to the capital markets through catastrophe bonds (H.R. 2555/S. 505), (2) a provision 
for a tax-free accumulation of reserves to pay catastrophe losses (H.R. 998/S. 1486), (3) a 
Treasury program to guarantee state-issued debt (H.R. 4014/S. 886), (4) a federal reinsurance 
backstop (H.R. 83), (5) a provision to establish individual catastrophe savings accounts (S. 1484), 
and (6) establishing a bipartisan commission to examine catastrophe risks and make 
recommendations for the management and financing of such risks (S. 1487).  
H.R. 2555/S. 505 (Klein/Nelson). The Homeowners Defense Act of 2009 would facilitate the 
expansion of the market for securitized insurance risks.15 These bills would create a National 
Catastrophe Risk Consortium (“Consortium”) that would allow states to pool large natural 
catastrophe risks within the Consortium and then transfer them to the private capital markets 
through the issuance of catastrophe bonds. The Consortium is premised on finding a low-cost 
catastrophic-risk-financing solution that generates market competition by exposing risk-transfer 
opportunities in a way that makes evident the cost savings for participants using the system, 
possibly in real (or near real) time. On March 10, 2010, the House Financial Services, 
Subcommittee on Housing and Community Opportunity and Subcommittee on Capital Markets, 
Insurance, and Government Sponsored Enterprises held a hearing on H.R. 2555. A mark up on the 
bill is expected in April 2010. 
H.R. 998/S. 1486 (Rooney/Nelson). The Policyholder Disaster Protection Act of 2009 would 
amend the Internal Revenue Code to allow insurers to accumulate tax-deferred reserves for 
catastrophe losses such as windstorms, earthquakes, fires, or floods.  
H.R. 4014/S. 886 (Sanchez/Nelson). The Catastrophe Obligation Guarantee Act of 2009 would 
authorize the Secretary of the Treasury to establish a program to provide guarantees for debt, 
including principal and interest, issued by state catastrophe insurance programs to assist in 
financing recovery from natural catastrophes. The guarantees for eligible state programs that 
cover earthquake peril shall not exceed $5 million and $10 million for all other perils. The bill 
also has a provision designed to encourage and support programs to mitigate losses from natural 
catastrophes for which the state insurance or reinsurance program was established to provide 
insurance coverage. 
H.R. 83 (Brown-Waite). The Homeowners’ Insurance Protection Act of 2009 would create a 
federal reinsurance mechanism to encourage states to establish catastrophe funds for 
homeowners’ insurance. The program would help states better prepare for and protect their 
citizens against natural catastrophes, encourage and promote mitigation, and finance recovery 
after a catastrophic event.

S. 1484 (Nelson). The Catastrophe Savings Accounts Act of 2009 would amend the Internal 
Revenue Code of 1986 to create catastrophe savings accounts. 
S. 1487 (Nelson). Commission on Catastrophic Disaster Risk and Insurance Act of 2009 would 
establish a bi-partisan commission to examine the risks and recommend possible solutions for 
Americans living in natural-disaster-prone areas.
