By state

Where the year’s United States quakes of magnitude 2.5 and up were located. A state with none that year is not listed.

By country

Where the year’s quakes of magnitude 4.5 and up were located. Quakes at sea, away from any country, are not counted here.

What this means

The catalog is only as complete as the instruments of the time. Worldwide coverage of magnitude 5 and up dates from the 1960s, and of 4.5 from the 1990s; earlier years hold the large quakes and the ones near a station, so a low count in an early year means fewer instruments, not a quiet earth.

By year

Every year the USGS catalog covers.
