www.firstpost.com Why Google's Android earthquake alert failed to detect Delhi's tremors

Strong tremors were felt in parts of Delhi and north India after multiple earthquakes hit Nepal around 2.30 pm on Tuesday. However, Google, a week after launching its Android Earthquake Alert System, failed to alert users about the temblor. Turns out, the feature is not supported in India

Why Google's Android earthquake alert failed to detect Delhi's tremors
  • The Google Android Earthquake Alert System failed to detect tremors in Delhi and north India following multiple earthquakes in Nepal.
  • The feature was newly launched in India, in collaboration with the National Disaster Management Authority (NDMA) and the National Centre for Seismology (NCS), but was in a phased rollout, suggesting many users didn't have access yet.
  • Although designed to notify users during such events, no alerts were received on Android phones in the affected regions.
  • The alert system relies on Android phones' accelerometers to detect early tremors, estimate earthquake characteristics, and send out alerts.
  • Key requirements for the system to work include having location settings and Android Earthquake Alerts ON, and Wi-Fi or cellular data connectivity.
  • The failure in alerting users is attributed to the gradual feature rollout, which may take weeks to become operational nationwide.
