Google’s early warning system for earthquakes failed to provide accurate alerts during the devastating earthquake in Turkey in 2023, where over 55,000 people died. Although 10 million people received Google’s highest-level alerts within 98 miles of the epicenter, the system underestimated the earthquake’s magnitude, issuing a “take action” warning for a 7.8 quake instead of a more severe alert. With many residents asleep, the system missed notifying them effectively.
The alert system, available in nearly 100 countries, relies on data from Android devices, which dominate Turkey’s mobile market. While previously touted as effective, investigations revealed that many did not receive adequate warnings during the disaster.
After analyzing the situation, Google adjusted its algorithms, claiming improvements would enhance the system’s alert capabilities. Experts express concern about overreliance on this technology, emphasizing the need for transparency regarding its performance. Google maintains that the system is a supplementary tool, not a replacement for national warning systems, and continues to refine its operations.
