Since launching in 2021, our Android Earthquake Alerts System has sent 1B+ alerts. Now we’re expanding the system from 98 to nearly 200 countries and regions.
Proud how this technology can help in moments that really matter. As one example, when the devastating earthquakes hit Venezuela this year, millions of people outside the epicenter got alerts and could take cover before the shaking began.

Today we used @MyShakeApp to investigate how to interpret seismographs! And apparently a selfie I the teacher’s to celebrate of course 🙃 #geology #earthquakes
Israel gets new earthquake warning system. They use the same EPIC algorithm developed @BerkeleySeismo for #ShakeAlert. Congrats to all those involved! timesofisrael.com/israel-get… via @timesofisrael
Now we are able to issue earthquake alerts, the challenge remains to help people respond and protect themselves. Great review from @DareBaldwin. Don't forget to download @MyShakeApp! theconversation.com/shakeale… via @ConversationUS
Congrats to those who participated in the #earthquake #ShakeOut yesterday and received the @MyShakeApp test alert. This is why we have early warning alerts: 30 sec to get ready for shaking in #eqnz yesterday

Just got the @MyShakeApp test #earthquake alert for #ShakeOut. I have the free @MyShakeApp on my phone, and it sends the alert to my watch. MyShake sent the alert to 727,956 phones across CA and OR! Ready for the next quake...
