Earthquake tops the risk list, and FEMA has declared Alaska a disaster area 94 times since 1953. Here's what to prepare for — and how.
Alaska faces one of the most demanding natural hazard profiles of any U.S. state, shaped by its position on the Pacific Ring of Fire, its vast subarctic and arctic climate zones, and its remoteness from mainland supply chains. Earthquakes and severe winter storms rank as the highest risks, while wildfires and flooding present serious seasonal threats across much of the interior and coastline. The 1964 Good Friday Earthquake — magnitude 9.2, the most powerful ever recorded in North America — devastated Anchorage, Valdez, and Kodiak, killing more than 130 people and triggering tsunamis that caused destruction as far as California. In the summer of 2019, the Swan Lake Fire on the Kenai Peninsula burned more than 167,000 acres, forcing evacuations and blanketing Southcentral Alaska in hazardous smoke for weeks. More recently, in 2026, the remnants of Typhoon Halong drove severe storms and widespread flooding across coastal and interior communities, earning a federal major disaster declaration. These events underscore a consistent pattern: Alaska residents can face cascading, multi-hazard emergencies with limited immediate outside assistance due to the state's geography. That reality places an especially high premium on household readiness — maintaining two weeks or more of food, water, and fuel; securing structures against seismic and wind loads; and knowing local evacuation routes before a disaster strikes.
Earthquakes strike without warning — structural damage and broken water mains are common.
Extended winter storms knock out power for days — prepare to survive without heat.
Wildfires can spread faster than a car — pre-evacuation planning saves lives.
Flooding is the most common US disaster — just 6 inches of moving water can knock a person down.
This densely populated region faces the greatest earthquake risk in the state, sitting near the Anchorage seismic zone, while also experiencing significant wildfire and severe winter storm exposure.
The wet, mountainous Southeast Panhandle is most vulnerable to flooding, landslides triggered by heavy rainfall, and severe coastal storms fed by Pacific weather systems.
The Interior experiences Alaska's most extreme winter conditions — including record cold snaps and blizzards — along with significant summer wildfire risk driven by lightning and dry boreal forest conditions.
Remote coastal communities in this region are highly exposed to storm surge, coastal erosion accelerated by thawing permafrost, and punishing winter storms with very limited evacuation or rescue infrastructure.
This region sits atop one of the world's most active volcanic and seismic zones, making earthquakes, tsunamis, and volcanic ash fall the dominant life-safety concerns.

The state's official emergency management agency — alerts, shelter info, and disaster assistance.
Alaskans receive official emergency alerts through the Alaska Emergency Alert System (EAS) and federal Wireless Emergency Alerts (WEA) sent directly to cell phones; additional local notifications may be available through individual borough or municipal emergency management offices.
What natural disasters is Alaska most at risk for?
Alaska's highest risks are earthquakes and severe winter storms. The state also faces medium-level threats from wildfires — particularly in the boreal interior — and flooding along rivers and coastlines. Its location on the Pacific Ring of Fire means seismic and volcanic hazards are ever-present, and its climate makes prolonged winter emergencies a recurring reality.
How many federal disaster declarations has Alaska received?
Alaska has received 94 unique FEMA disaster declarations, including 66 major disaster declarations (DR-level). The most common incident types have been fires, severe storms, and floods. The most recent major declaration, in 2026, addressed severe storms, flooding, and the remnants of Typhoon Halong affecting communities across the state.
How should Alaska households prepare for an earthquake?
Residents should secure heavy furniture and water heaters to walls, store at least two weeks of water and food — longer for rural areas — and identify safe spots in each room to drop, cover, and hold on. Because infrastructure damage can isolate communities for days or weeks, a household go-bag and an out-of-state contact for family communication are also strongly recommended.
How do Alaskans receive official emergency alerts?
Alaska uses the Alaska Emergency Alert System (EAS) and the Wireless Emergency Alert (WEA) system, which pushes geotargeted alerts to cell phones automatically. Residents can also register for local borough or municipality notification systems and should monitor the Alaska Division of Homeland Security and Emergency Management for statewide advisories during major incidents.
