Why Alaska is seismically active
Alaska experiences more large earthquakes than the rest of the United States combined. The 1964 Great Alaska Earthquake reached magnitude 9.2, the largest ever recorded in North America. The Aleutian Trench, where the Pacific plate dives beneath the North American plate, drives near-constant seismic activity along the state's southern arc.
