Earthquakes
Earthquakes strike without warning, and the first numbers often shift in the hour after as seismologists review the data. This page collects the quakes we have put on the board, newest first, each tied to its official USGS event page. Magnitudes, depths and tsunami flags are the agencies’ figures as published. When a tsunami warning center speaks, its word outranks ours.
