Apparently slept right through and never felt the 4.0 El Cerrito/East Bay earthquake this morning. Also USGS Shake Alert /did not/ activate for me. #quakestodon #ShakeAlert #earthquake #sfba #sanfrancisco #SFBay
Well, now I know that the #ShakeAlert app on my phone works. Everybody ok? #Earthquake #sfba
I hope everyone is ok, but it's really cool to see #ShakeAlert work #earthquake
What “shakealert” means
WikipediaShakeAlert is an earthquake early warning system (EEW) in the United States, developed and operated by the United States Geological Survey (USGS) and its partners. As of 2021, the system issues alerts for the country's West Coast. It is expected that the system will be expanded to other seismically active areas of the United States in the future. ShakeAlert is one of two EEW systems available in the United States, with Google's Android Earthquake Alerts System being the other.
