Is Your Phone Ready for the Next Earthquake? Here’s What to Do

Smartphones have evolved beyond communication tools to become vital instruments in earthquake detection and early warning systems. By leveraging built-in sensors and specialized applications, these devices can alert users moments before seismic shaking begins, potentially saving lives.

A powerful 7.7-magnitude earthquake struck Myanmar at 1:20 PM (local time) on March 28, 2025, with tremors felt as far as Bangkok, Thailand. The quake occurred at a depth of 10 km, with its epicentre at 96.07°E, 21.93°N.

How Smartphones Detect Earthquakes

Modern smartphones are equipped with accelerometers that detect motion. When a network of phones senses simultaneous ground movement, this data can be analyzed to identify seismic activity, enabling the issuance of timely alerts.

How To Enable Earthquake Alerts on Your Smartphone

To receive earthquake alerts:

Android Users: Google's Android Earthquake Alerts System is integrated into devices running Android 5.0 and above. It uses your phone's accelerometer to detect earthquakes and can send alerts seconds before shaking occurs. Ensure your device has location services enabled and that earthquake alerts are activated in your settings.

iOS Users: While iPhones don't have a built-in earthquake detection system, users can download third-party apps like MyShake. Developed by the Berkeley Seismological Laboratory, MyShake provides early warnings and collects seismic data from users worldwide. After installing, follow the app's setup instructions to enable alerts.

Earthquake Alerts on Smartphones

The Android Earthquake Alerts System has expanded its coverage to all 50 U.S. states and six territories, enhancing nationwide preparedness. This system utilizes a vast network of Android devices to detect and alert users about earthquakes, providing crucial seconds to take protective actions. 

However, challenges remain. In February 2025, Google's earthquake detection feature issued false alerts in São Paulo and Rio de Janeiro, Brazil, prompting its temporary disablement in the region. Google is investigating the incident to improve the system's accuracy. 

Smartphone-based earthquake detection represents a significant advancement in public safety. By enabling these alerts, users can gain precious seconds to protect themselves during seismic events. As technology evolves, these systems are expected to become more accurate and widely available, contributing to global disaster preparedness.
