The screenshot shared by Sundar Pichai has written that there is an Earthquake at 11:42. You may have felt shaking and it is estimated M4.8 about 23.8 miles away.

What is ShakeAlert?

It is an earthquake early warning (EEW) system that detects significant earthquakes so quickly that alerts can reach many people before shaking arrives. It’s not earthquake prediction, but it warns people that an earthquake has begun and shaking is imminent.

How does it work?

The app works along with the U.S Geological Survey (USGS) with a coalition of State and University partners. The USGS and its partners are continuing to expand these applications in coordination with state agencies in Washington, Oregon, and California. The California Governor's Office of Emergency Services has funded the app thus far.
