About these figures

Magnitudes, locations and times come from the U.S. Geological Survey. Earthquakes in the United States are listed from magnitude 2.5; times are Eastern. The first figures for a new earthquake are calculated automatically and are often revised in the following minutes and hours, so a magnitude here can change. "Felt reports" counts the people who told USGS they felt the shaking. The USGS impact alert (yellow, orange or red) is its estimate of possible deaths and damage. A tsunami flag means USGS marked a large earthquake in an ocean region; it is not a warning. Tsunami warnings come from the National Weather Service's Tsunami Warning Centers.
