Google admits earthquake alert failure before deadly 2023 Turkey quake: Report

Google has come under fire for significant flaws in its Android Earthquake Alerts (AEA) system, which failed to deliver timely warnings before the catastrophic earthquake that hit Turkey in February 2023. This disaster was one of the most lethal in the nation's recent past, claiming over 55,000 lives and injuring more than 100,000 individuals. Despite the system's capability to alert millions in the quake-affected area, reports indicate that only 469 critical 'Take Action' notifications—intended to prompt immediate protective actions—were dispatched prior to the 7.8-magnitude earthquake. This seismic event struck at 4:17 AM local time, a moment when many were asleep and unprepared. In contrast, approximately 500,000 people received the less urgent 'Be Aware' notifications, which are designed for minor tremors and do not prompt life-saving behavior. The shortcomings of the AEA system have been linked to a grave miscalculation of the earthquake's magnitude. Initially, it was estimated to be between 4.5 and 4.9, a vast underestimation of the actual seismic activity. This misjudgment severely curtailed the alerting capabilities of the system. Following investigations by the BBC and independent experts, Google acknowledged in a paper published in Science that its detection algorithms contained significant flaws. In response to the criticism, Google conducted a simulation of the event using an updated version of the AEA system, claiming it would have issued 10 million 'Take Action' alerts and 67 million 'Be Aware' notifications had the new system been operational. A second major earthquake that occurred the same day saw a somewhat better response, with over 8,000 'Take Action' alerts sent and nearly four million 'Be Aware' notifications issued. However, experts argue that the damage caused by the initial failure was irreversible, costing vital seconds for warning. Elizabeth Reddy, an assistant professor at the Colorado School of Mines, expressed her frustration regarding the delayed disclosure of these issues, stating, "This wasn’t a minor incident; people died, and the warning system did not perform as needed." The AEA operates independently of government warning services, relying on data from Android devices, which represent over 70% of mobile phones in Turkey. Google insists that the AEA is designed to complement national alert systems rather than replace them. Nevertheless, seismologists and emergency management specialists caution that some countries may become overly dependent on Google’s system, potentially undermining the establishment of robust public warning infrastructures. Harold Tobin, director of the Pacific Northwest Seismic Network, raised concerns about this reliance, asking, "Would some places make the calculation that Google’s doing it, so we don’t have to? Transparency about its effectiveness is critical."
