Google’s Android Earthquake Alerts system failed to properly alert users about the 7.8 magnitude earthquake that hit Turkey in early 2023, resulting in thousands of deaths. The system, which uses phone sensors to detect early signs of an earthquake, did not send critical alerts to most users in the affected area.
According to Google, the system partially failed, sending lower-level “BeAware” warnings to half a million users but only full “TakeAction” alerts to 469 people. Experts estimate that up to 10 million people within 98 miles of the epicenter could have benefited from alerts.
Google attributes the failure to limitations in its detection algorithms and confirms that the system worked correctly on later aftershocks. The company has published a study on the Android Earthquake Alerts system, which found that users value being informed about potential hazards in their area, appreciate the right type of alert, and take action when prompted.
The study’s findings show that 79% of people who received an alert but didn’t feel the earthquake found it helpful, while those who received a “TakeAction” alert reported feeling strong shaking more often. The most common response to these alerts was to drop, cover, and hold on. Google is continuing to learn from user feedback as the system evolves.
In related news, Google has announced plans to improve its Android Earthquake Alerts system, including showing alerts on smartwatches via Wear OS.
