After a major earthquake in California, the ground keeps moving: aftershocks are smaller quakes triggered as the crust adjusts around the fault that ruptured. They are most frequent right after the mainshock and taper off over days to months. This page tracks recent seismic activity across California live, so you can follow an aftershock sequence as it happens. For instant alerts the moment a new aftershock strikes near you, the free QuakeMate earthquake alert app sends real-time push notifications.

Aftershocks in California - FAQ
Are there aftershocks in California right now?
Yes. 89 earthquakes have been recorded in California in the last 24 hours. The live feed above lists each one as it is detected, so you can watch an aftershock sequence unfold in real time.
How long do aftershocks last after a big earthquake in California?
Aftershocks are most frequent in the hours and days right after the mainshock and taper off over time, but a large earthquake can produce aftershocks for months. Their number and size follow well-known patterns (Omori and Bath laws), so activity gradually declines even though individual aftershocks can still be strongly felt.
