An App is now available in the US that issues a warning that an earthquake is expected soon. Called ShakeAlertLA, the app has been launched in Los Angeles. It employs mobile technology to warn the LA residents when the US Geological Survey?s early-warning sensor network shows that an earthquake of magnitude 5.0 or beyond is about to hit their location.
The warning comes a few seconds before the earthquake. For some, a warning that is a?few seconds early may not seem like that big a deal, but according to LA Mayor, Eric Garcetti, with earthquakes, ?getting a few seconds? heads-up can make a big difference if you need to pull to the side of the road, get out of an elevator, or drop, cover, and hold on.?
The app is available for both, Apple and Android smartphones. For now, it is only available for the state of LA. While there are many public service agencies across the west coast that utilize the USGS? early warning sensor network to detect earthquakes, it is the first time the residents have some?technology available to receive alerts immediately across the region.
Moreover, existing alerts are too slow. ?The purpose of early warning is to get people into that safe place before the shaking starts instead of once the shaking starts,? says the Mayor.
?If you have a few seconds, you can get under a sturdy table, you can get away from that bookcase, you can move away from hazardous materials, you can move away from the places you are likely to be injured.?
“It will never be perfect, but this will give you a notification for the majority of earthquakes hitting the southland,” Mayor Garcetti said. “But while we?re waiting for a something perfect, I don?t want to wait to launch a system that can help save lives.”
