Google has announced the launch of its earthquake alert system for Android devices in India. The system uses smartphone sensors such as accelerators, which can act as small seismometers to detect tremors.

The company on Wednesday said the system, developed with consultation from the National Disaster Management Authority (NDMA) and the National Seismology Center (NSC), will provide early earthquake alerts for Android users in an area that’s likely to be impacted. These alerts will be available in local Indian languages supported by Android.

The company sends two types of alerts: Be Aware and Take Action. The “Be Aware” alerts are sent to users experiencing MMI 3 & 4 shaking during an earthquake of magnitude 4.5 or greater. It just shows an alert on your screen and doesn’t play any sound if your phone is on Do Not Disturb mode or in silent mode.
