Alaska: Overview

Download all of Alaska as PDF Print

Everything in the main manual and the skill guides applies in Alaska exactly as written. What’s different here is the specific hazard profile and the state, local, and legal context around it. This page is the starting point; the other three pages under Alaska go deeper on laws, local resources, and the data behind the risks named here.

The 1964 Good Friday earthquake: the most powerful ever recorded in North America

On March 27, 1964, a magnitude 9.2 earthquake struck Alaska, the most powerful earthquake ever recorded in North America and the second most powerful recorded anywhere since modern seismography began. The shaking lasted four and a half minutes and deformed more than 200,000 square kilometers of terrain. Fifteen people died in the earthquake itself, and 124 more died in the tsunamis it triggered along the Alaska, Oregon, and California coastlines, including a wave that reached 220 feet at Shoup Bay. See the Risks page for the full data.

October 2025 Typhoon Halong remnants: a very recent, still-unfolding disaster

In October 2025, the remnants of Typhoon Halong slammed into Alaska’s Yukon-Kuskokwim Delta with hurricane-force winds and coastal flooding that reached up to 60 miles inland, an area hundreds of miles from the nearest road system. Homes floated off their foundations with families still inside, utility poles snapped, and the storm triggered one of the largest airlift evacuations in Alaska’s history. This page treats it as a live, recent event rather than settled history; recovery and even relocation decisions for affected villages were still ongoing as of early 2026. See the Risks page for the full data.

What this means for how you use the rest of this manual

The manual’s Tier structure and the skill guides apply without modification, but Alaska adds a structural constraint most of this manual doesn’t otherwise address: roughly 60% of Alaska’s 285 communities have no state-registered fire department, and many rural communities are reachable only by plane or boat, weather permitting. That means the assumption running through most of this manual, that professional emergency responders will eventually arrive, holds far less reliably here than almost anywhere else covered on this site. Self-sufficiency and community-level mutual aid aren’t just Tier 3-4 aspirations in remote Alaska; they’re closer to a baseline necessity.
