What drives the risk for expensive homes in Alaska
- Catastrophe exposureEarthquake is Alaska's defining catastrophe risk. The magnitude 9.2 Great Alaska Earthquake of March 27, 1964, centered in the Prince William Sound region, is the largest recorded earthquake in U.S. history, and Anchorage sustained heavy property damage. The USGS notes that Alaska has more large earthquakes than the rest of the United States combined. Source
- FloodIn Juneau's Mendenhall Valley, the glacier-dammed Suicide Basin has drained about 48 times since 2011, and its outburst floods have grown. The Mendenhall River peaked at 14.97 feet in 2023, 15.99 feet in 2024 and a record 16.65 feet on August 13, 2025, when the City and Borough of Juneau counted 35 homes affected, some with 4 to 5 feet of water in living spaces. Flood is excluded from homeowners policies, and NFIP building coverage stops at $250,000. Source
Alaska by the numbers
| Measure | Alaska | Rank among the states | Detail |
|---|---|---|---|
| Federal major disaster declarations since 2000 | 46 | #7 (tied) of 51 | Most often for severe storm (23), flood (12), mud/landslide (5). Lower Kuskokwim Regional Educational Attendance Area has been in 15 of them. |
| National Flood Insurance Program claims, 2005–2025 | 453 | #47 of 51 | $13.3 million paid; 37% of claims with a known flood zone were outside FEMA’s high-risk zones. |
| Hail reports, 2016–2025 | 5 | #50 of 51 | 0 of them 2 inches or larger. Largest stone 1 inches, Kuskokwim Delta County, June 2018. |
| Tornadoes, 2016–2025 | 1 | #50 of 51 | 0 rated EF2 or stronger; 5 recorded since 1950. |
| Earthquakes of magnitude 4.0+, 2000–2025 | 8,331 | #1 of 51 | Largest: magnitude 8.2, 2021 Chignik, Alaska Earthquake, July 29, 2021. |

When the standard market says no, and what earns credits
- Insurer of last resort and wind poolsAlaska has no FAIR Plan: it does not appear among the states in the fiscal 2024 FAIR Plan data compiled by the Property Insurance Plans Service Office (PIPSO) and published by Triple-I. With no state insurer of last resort for homes, a house the standard market declines is generally placed with a surplus lines insurer. Source
- Mitigation credits and programsAlaska has no statewide residential building code. The strict codes the state adopted after the 1964 earthquake do not apply to homes of three units or fewer, and Eagle River and Chugiak (inside the Municipality of Anchorage) and the Matanuska-Susitna Borough have no residential codes. A 2021 University of Alaska Anchorage-led study of the November 2018 earthquake found building damage rates in those areas 18 to 20 times higher than in the part of Anchorage where codes are mandated.

Worth knowing in Alaska
Most residential property policies in Alaska do not cover earthquake damage, so it is bought as a separate policy. The Division of Insurance says the earthquake deductible may be 10 to 20 percent of the coverage limit, and that the earthquake dwelling limit usually matches the homeowners limit, so a home that is underinsured for fire is underinsured for earthquake too.

Where can an expensive home in Alaska get coverage if insurers decline it?
Alaska has no FAIR Plan: it does not appear among the states in the fiscal 2024 FAIR Plan data compiled by the Property Insurance Plans Service Office (PIPSO) and published by Triple-I.

Is flood insurance enough for a high-value home in Alaska?
In Juneau's Mendenhall Valley, the glacier-dammed Suicide Basin has drained about 48 times since 2011, and its outburst floods have grown.
