Earthquakes in United States

The United States spans some of the most seismically active ground on the planet. Alaska and its Aleutian arc rank among the busiest subduction zones anywhere; California rides the San Andreas transform between the Pacific and North American plates; the Pacific Northwest sits above the Cascadia megathrust; and Hawaii shakes with the movement of magma beneath its volcanoes.

The 1964 Great Alaska earthquake (M9.2) is the largest ever recorded in North America and the second largest in the world. Elsewhere the 1906 San Francisco quake reshaped a city, and even the stable central states carry a memory of the enormous 1811–12 New Madrid earthquakes.

The figures below are drawn live from the EarthquakeIndex archive for the area shown. No one can predict when the next earthquake will strike — but you can follow every event the moment EMSC records it.
