Only 20% of Oregonians Insured for Earthquake Risks

January 19, 2010

Although Oregon is among the states at highest risk for a major earthquake, only about 20 percent of Oregonians have earthquake insurance, according to a Department of Consumer and Business Services (DCBS) survey.

“Consumers may want to think about their ability to rebuild if their house is destroyed in an earthquake,” said Cory Streisinger, director of the Department of Consumer and Business Services. “Insurance should be weighed as part of other earthquake preparations.”

Later this month, on Jan. 26, Oregon marks the 310th anniversary of the last, great Cascadia Subduction Zone earthquake. This magnitude 9.0 earthquake was centered about 75 miles offshore and damaged the coastline from Northern California to Southern British Columbia, according to the Oregon Department of Geology and Mineral Industries.

A 10,000-year geologic record shows these mega-quakes occur every 300 to 600 years, putting Oregon within the window of a major earthquake, said James Roddey, earth sciences information officer with that agency. Damaging earthquakes have also occurred within the past 16 years in different parts of the state, causing tens of millions of dollars worth of damage.

“Earthquake and tsunami preparedness should be a part of everybody’s emergency plan,” said Roddey. “We live in earthquake country. You need to be prepared.”

The DCBS Insurance Division last year surveyed 20 insurance companies that account for 80 percent of the homeowner insurance premium in the state. The findings:

  • Homeowners generally can buy earthquake insurance as an endorsement (addition to their policy) or as a separate policy. The few companies that do not offer earthquake insurance in Oregon typically refer clients to a company that sells stand-alone earthquake policies.
  • Earthquake coverage is often less than $300 a year for a $300,000 wood-frame home. Masonry homes are more expensive to insure. Older homes should think about bolting the home to the foundation or making other seismic upgrades before buying earthquake insurance. To keep premiums low and because it is designed to cover catastrophic loss, earthquake coverage generally features high deductibles. These typically amount to 10 percent or 15 percent of the amount.
  • A homeowner with a house insured for $300,000 and a 10 percent deductible would pay $30,000 before the policy would pay. Coverage for contents is separate.

Consumers who wait to buy insurance until after a tremor will be too late: Insurance companies typically suspend sales of earthquake insurance for a period of time after a seismic event, DCBS said.

“No one knows for sure when a major earthquake will strike but Oregon homeowners may want to at least talk to their insurance agent about this coverage,” said Teresa Miller, administrator of the Insurance Division.

Studies by the Federal Emergency Management Agency (FEMA) show the bulk of the nation’s annual losses from earthquakes are expected to occur in California, Oregon and Washington — with most of that loss in California.

Although quake-prone California collects more earthquake premiums than any other state, the insurance costs significantly more than in Oregon and only about 12 percent of Californians are covered for earthquakes. The state created the California Earthquake Authority to ensure homeowners could buy earthquake insurance after the 6.7-magnitude Northridge Earthquake of 1994, the costliest quake in U.S. history.

The majority of economic loss is along the West Coast but earthquake risk is nationwide. About 35 percent of Missouri residents, who are part of the New Madrid seismic zone in the central Mississippi Valley, are insured for earthquakes. The last major earthquake in that area, a magnitude 8, occurred in late 1811 and early 1812 and caused some sections of the Mississippi River to appear to run backwards and church bells to ring as far away as Boston.
