The next big US earthquake is overdue. What if you could know about a quake before it strikes? Now you can with Early Warning Labs' QuakeAlert app, a free app that gives a warning up to 60 seconds before a dangerous quake.

With the 20 seconds of pre-shake warning you’re able to drop to the floor, crawl under your desk, and hold on. As the building begins to shake, you see a huge framed piece of artwork fall from the wall directly onto the chair where you were sitting.
Thanks to the QuakeAlert App, you’ve avoided major injury, and have the peace of mind that you’ll be ready for the next one.
Early Warning Labs is an official ShakeAlert commercial partner.
The QuakeAlertUSA app is powered by data from the USGS ShakeAlert Earthquake Early Warning system.
Alert delivery and other features provided by QuakeAlertUSA are being tested and there are no implied guarantees.
