#EQhistory: July 1952 M7.5 Kern County. While we tend to remember eqs by the main shock, it is important to note that it isn't always the cause of the worst damage. Substantial damage and 2 fatalities occurred in the aftershock sequence, which included 6 events > M5 on the same

Did you feel the M4.4 earthquake near Muscoy, CA, a few minutes ago? The ShakeAlert earthquake early warning system was activated. ShakeAlert estimated the magnitude at M4.7, which meets the criteria for issuing alerts to cell phones in the area near the earthquake. We'd love to.

Notice the distinct long-period waves, with shaking that lasted for tens of minutes across our network. Events this large serve as powerful reminders of how powerful the Earth is, and will likely bring many new discoveries as research is conducted.

The M8.8 Kamchatka earthquake yesterday was so massive its seismic waves traveled around the world—reaching Southern California ~10 minutes later. While we focus on local events, the #SCSN also detects and catalogs major global quakes. Here's how those waves looked on our Live.
