The United State’s first publicly available earthquake early-warning app, ShakeAlertLA, has been unveiled at Los Angeles.
The app will warn people if the US Geological Survey’s early warning sensor network indicates an earthquake of 5.0 magnitude or larger.
Many expect the app will prompt more cities across the country to invest more in such early warning technologies.
Earthquakes are a matter of when — not if. We’re officially launching #ShakeAlertLA tomorrow, and today you can become one of the first to use our early warning technology.

Currently available options such as amber alerts and the presidential alert are reported to be very slow.
The ShakeAlertLA is a pilot project, in collaboration with the US Geological Survey (USGS), AT&T and The Annenberg Foundation, that combines the USGS ShakeAlert earthquake early warning sensor network with mobile app technology.
The app is developed in open source, which allows it to be replicated by other cities, counties, and states.
Here’s how the new #ShakeAlertLA works-the farther away from the epicenter..the longer the warning..Seismic “P-Waves” (or primary waves), on average, travel about 4 miles per second-Therefore, if you are 20 miles from the epicenter you will receive about a 5 second warning @FOXLA

Playing with the @ShakeAlertLA app.
They give some disclaimers. Smart to do so. It’s very likely we’ll get false alerts but that doesn’t mean it’s worth ignoring. pic.twitter.com/OjkDBY4dBM
