About ShakeAlertLA App
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.
Version 1.1 adds a new feature based on feedback from the ShakeAlertLA community. The "Recent earthquakes" screen now displays earthquakes of magnitude 3.0 and above in the past 30 days for the continental United States.

What's new in version 1.3
This version allows notifications to be sent to ShakeAlertLA users in Los Angeles County who could potentially experience weak shaking or greater from earthquakes of magnitude 4.5 or greater within Los Angeles County. This has been lowered from the previous setting of magnitude. The time shown for earthquakes has been changed from Universal Time Coordinated (UTC) to show Pacific Standard/Daylight Time (PST/PDT). This update also provides interruption (do not disturb) setting options to allow users to choose to be notified of an event even when on silent mode. An explanation is also provided on how the location data is being used, and adds a link to a demo of what an alert will look and sound like.
