Google’s Earthquake Warning System Failed During Turkey’s 2023 Earthquake

Google has acknowledged that its earthquake early warning system did not properly alert millions of people during the deadly earthquake in Turkey in 2023. The 7.8 magnitude quake struck near the city of Gaziantep, and although the system was capable of sending out an early warning to approximately 10 million people, only a small fraction of them received a ‘Take Action’ alert, which is intended for high-magnitude quakes. Instead, a lower-level warning meant for lighter tremors was sent to roughly half a million people, which did not stand out enough to prompt immediate action. Despite previous claims that the system had performed well in 2023, an investigation revealed that its effectiveness was much lower than expected. Google’s Android Earthquake Alerts (AEA) system is operational in nearly 100 countries and provides users with vital information during seismic events. However, this failure to notify citizens in Turkey highlights the limitations of relying on a tech company’s global system rather than national authorities or more localized efforts. Google’s system is often seen as a crucial safety net in countries without their own warning infrastructure, but the system’s limitations became evident in this case.
