MyShake notifications are simple, and won't display how strong the earthquake is or where its epicenter is located. MyShake also provides users with helpful information about how to prepare for the inevitable next earthquake, and uses your phone's accelerometers to collect ground shaking data to help scientists improve the app's accuracy. These alerts will be sent to users regardless of whether they’ve downloaded the app. Part of the California Earthquake Early Warning System, the app will also work in conjunction with Wireless Emergency Alerts system-the blaring notifications that flash on all phone screens in the event of an Amber Alert, wildfire, or hazardous weather conditions. Users in the Central Coast were given a 1.6-second heads up before the shaking began. In the case of the Bay Area quake, alerts reached users in a median time of about 2.1 seconds, Allen told the San Francisco Chronicle. Scientists successfully tested the app this week after two earthquakes, a 4.5 and 4.7, struck the Bay Area and the Central Coast. But, he stressed, “we feel like it’s at a point where we can really make a difference. It’s certainly not a flawless system-some alerts may come late and the system may miss some earthquakes, Allen told the Los Angeles Times. At the moment, the MyShake app is set to alert iOS and Android users in the event of a 4.5 magnitude earthquake or stronger. In the seconds after an earthquake occurs, nearby seismic sensors pick up on the shaking and send a push notification to users, alerting them that they may soon feel shaking. The shaking waves of an earthquake travel across Earth’s surface at speeds of around 0.5 to 3 miles per second, according to the USGS. ![]() “Finally, an earthquake early warning system is here for the whole state of California.” Berkeley seismologist Richard Allen said in a press conference. Berkeley and its partners announced a new update to the MyShake App, which will give users several seconds of warning before they feel the shaking of an earthquake occurs. On the 30th anniversary of California's Loma Prieta Earthquake, which killed 63 people in October 1989, U.C. Even a few seconds of warning could help people prepare for intense shaking. ![]() Uists developed the app to alert users to shaking caused by a magnitude 4.5 earthquake or greater.
