Google’s Earthquake Alert Failed in Turkey Quake—Millions Left Unwarned

In February 2023, a pair of catastrophic earthquakes struck Turkey and Syria, leaving tens of thousands dead and millions affected. At a time when seconds could have saved lives, Google’s Android Earthquake Alerts System failed to notify the vast majority of people within the danger zone. Only a small fraction of users received timely warnings, raising critical questions about the reliability of smartphone-based early alert systems.

Google has since acknowledged that its Earthquake Alerts System underperformed dramatically during the disaster. According to its internal analysis, only 469 users received the high-priority “Take Action” alert before the magnitude 7.8 quake hit at 4:17 a.m. local time. This type of alert is designed to wake users and prompt them to immediately seek safety. Around 500,000 more received a lower-tier “Be Aware” notification, which doesn’t override silent or Do Not Disturb settings. In total, over 10 million people were within the 160-kilometer radius of the quake’s epicenter, many of whom could have benefited from a more aggressive alert system.

The core issue appears to have been an initial underestimation of the earthquake’s magnitude. Google’s sensors and algorithm misjudged the quake as being much weaker, initially placing it between 4.5 and 4.9 magnitude. This resulted in the system failing to escalate the warning to the level necessary to trigger urgent alerts. As a result, many users slept through the critical window during which they could have taken protective action.

In response, Google engineers reanalyzed the event and simulated how the system would have behaved using updated algorithms. The revised model would have delivered “Take Action” alerts to 10 million people and “Be Aware” alerts to over 67 million globally. This significant discrepancy reveals just how much difference accurate early detection can make in preventing injuries and fatalities.

Since its launch in 2020, Google’s Android Earthquake Alerts System has aimed to fill a vital gap in early warning capabilities, particularly in regions without robust government infrastructure. The system uses accelerometers in Android phones to detect seismic activity and rapidly distribute alerts. It has now expanded to over 90 countries and continues to evolve through machine learning and field testing.

Despite the promise of the technology, experts argue that the system’s failure in Turkey underscores the need for multiple layers of early warning. Relying solely on commercial technology, no matter how advanced, is not a substitute for state-run systems with dedicated hardware, extensive data integration, and continuous monitoring by trained seismologists.

Critics also emphasize that Google did not disclose these shortcomings until academic research shed light on the gap between what the system was supposed to do and what it actually achieved. Transparency in performance reviews and collaboration with seismological institutions are essential to improve trust and effectiveness going forward.

To its credit, Google has incorporated feedback and lessons learned from the Turkey quake into system upgrades. These include better calibration of magnitude thresholds and more aggressive push notifications for suspected large-scale seismic activity. The company remains committed to expanding and refining the alerts globally, but the incident has made it clear that the technology alone is not enough.

The Turkey-Syria earthquake served as a grim test case for early warning systems in the real world. While smartphones can help distribute alerts rapidly, they still rely heavily on accurate detection and timely escalation. Moving forward, governments, tech companies, and emergency agencies must work hand-in-hand to ensure no one is left vulnerable in the face of natural disasters.
