Google has used motion sensors in more than 2 billion mobile devices to create an earthquake early warning system that is as effective as traditional seismometers, according to a new study.
Between 2021 and 2024, the company's Android Earthquake Alerts (AEA) system detected over 11,000 earthquakes using smartphone accelerometers and sent over 1,200 notifications to Android users in 98 countries.
The system has increased the number of people with access to earthquake warnings tenfold, from 250 million in 2019 to 2.5 billion today. The researchers published their findings July 17 in the journal Science.
