The Earthquake Network initiative
Real time earthquake alerts on your smartphone are possible thanks to Earthquake Network.
Started in 2012, this initiative implements a crowdsourced Earthquake Early Warning system based on networks of smartphones.
More than 25 million people took part in the initiative and the system has sent more than 8,400 real time earthquake alerts.
If you are not too close to the epicenter, you can receive the alert in advance and take cover before shaking arrives.
