Google Android Earthquake Alerts System Reportedly Underestimated Kahramanmaraş Earthquake and Failed to Send Urgent Warnings to Millions
During the February 6, 2023 Kahramanmaraş earthquake sequence, Google's Android Earthquake Alerts system reportedly estimated the initial magnitude-7.8 earthquake at only magnitude 4.5–4.9. Just 469 users reportedly received its highest-level "Take Action" warning, while approximately 500,000 received lower-level notices; researchers later estimated that roughly 10 million people could have received urgent warnings providing up to 35 seconds to seek safety.
