How to enable Android and iPhone earthquake alerts on smartphones

Android and iPhone devices can receive early earthquake warnings that arrive seconds before strong shaking. On Android, users open Settings → Security & emergency → Earthquake alerts and toggle the switch; the phone must have GPS and internet access and avoid extreme battery‑saving modes. On iPhone, the option is under Settings → Notifications → Government or Emergency alerts, again requiring location services.

The system uses the accelerometers of millions of devices to detect the first seismic waves and broadcast alerts. In Venezuela, the Google‑based service warned about 11.4 million users with up to 30 seconds of advance notice, a benefit highlighted by digital‑transformation specialist Francisco Ochoa. He also recommends complementary apps such as Earthquake Network, MyShake, and My Earthquake Alerts, and notes that communication tools like WhatsApp, Telegram or Google Maps help families locate each other after a quake.
