00:00moments before the ground starts shaking from an earthquake. People who live on
00:04the west coast may feel their phone vibrating. Anything we can do to reduce
00:10the amount of time between when we detect the earthquake in the field and
00:13when someone gets something on their phone or when a system reacts to it is
00:18really our goal. Shake alert. A new early warning system can alert people
00:22seconds before a magnitude five or greater earthquake strikes. It may not
00:27seem like a lot of time, but it can prevent injuries. I think it's really
00:31important for people to know that the amount of time they may get is probably
00:36pretty short, but even the shortest amount of times, even that awareness
00:40will allow them to take that protective action, drop, cover and hold on. All
00:43they need is a couple of seconds to do that. The USGS debuted shake alert in
00:47California, Oregon and Washington. By using data from sensors placed up and
00:53down the coast, scientists are able to detect earthquakes. What we produce is
00:58something called the shake alert message. It's a data package that
01:00contains information about what the estimated magnitude, the location and
01:05the potential shaking from an earthquake. We make that shake alert
01:09message available to one of our many partners who are out there. In order to
01:15receive the alerts, you must activate emergency notifications on your phone.
01:19You can do so in your settings. For AccuWeather, I'm Emmy Victor.
