We just experienced a 5.2 earthquake. It was centered in Julian, and I’m in Corona! It was nice having at least 10 seconds to prepare. This app works! We just experienced a 5.2 earthquake. It was centered in Julian, and I’m in Corona! It was nice having at least 10 seconds to prepare.

What can I say.. it worked a few seconds faster than the USGS and cal emergency system. And both were a few seconds ahead of a quake epicenter about 45 miles away.

This app has taken a lot of earthquake anxiety away from me. Being from the east coast I had never feeling an earthquake until I moved to California. The first earthquakes I ever felt were the Big Bear/Landers quakes and it scared me so much and I have bad anxiety anytime I feel a quake. This app takes that element of surprise away and gives me time to find a good place to go before it hits. I’d say a good 5-10 seconds, which doesn’t sound like a lot, but it’s enough to move to a safer place and takes that “surprise-the ground is shaking” away. It makes me so much less scared when the quake actually hits. We’ve had two bigger quakes since I installed it and both times, the early warning informed me before hand. Very thankful for this app!

I don’t know why the rating is so low. I have 5 apps downloaded to test which one I want to keep and this one is the only one that gave me a heads up before the earthquake hit 10 mins ago. I actually thought for a second I didn’t feel anything and then my house shook from a 4.5 quake. The other apps didn’t alert me until 10-30 seconds after it hit so it looks like I’ll be keeping this one and dumping the others. 10 second heads up I don’t know why the rating is so low.

We had a big one this morning in San Diego – 6.0. The notification system worked! Thank you! But users have to enable their location to get the notifications. Don’t forget to enable your location!
