ShakeAlertLA alerts you that an earthquake has been detected and that you may soon feel shaking. You can also use this app to prepare for an earthquake, get details on recent earthquakes, and find help after an earthquake. This app is brought to you by Mayor Eric Garcetti and the City of Los Angeles, and built on the ShakeAlert system developed by the U.S. Geological Survey.
This update notifies ShakeAlertLA users who may experience shaking from earthquakes of magnitude 4.5 or greater within Los Angeles County. This was previously magnitude 5.0 or greater. Event time now displays in Pacific Standard/Daylight Time. Interruption (do not disturb) setting options allow users to be notified of an event when on silent mode. An explanation is provided on how location data is being used. And, a link to a demo of what an alert will look and sound like is provided.
