Two years after twin earthquakes devastated parts of Turkey and Syria—killing nearly 55,000 people in Turkey and over 5,000 in Syria—Google has acknowledged that its Android Earthquake Alerts System failed to properly warn millions in the impact zone.
According to a BBC investigation, Google confirmed that its system did not deliver accurate or widespread alerts to the roughly 10 million people living within close proximity of the epicenter during the February 6, 2023 disaster.
What Happened?
The region was rocked by two massive quakes—magnitudes 7.8 and 7.7—in the early morning hours. The first struck at 4:17 a.m., when most residents were asleep. Experts say a properly delivered “Take Action” alert, the system’s most serious warning, could have woken people up and potentially saved thousands of lives.
However, Google only sent out 469 “Take Action” alerts during the first quake. Another 500,000 users received a lower-level “Be Aware” alert, typically meant for light to moderate shaking. In reality, tens of millions were within range of severe ground movement.
Google admitted that up to 10 million people within 98 miles of the epicenter could have received the highest-level alert, which may have offered a 35-second lead time—crucial seconds for survival.
Why Did It Fail?
Google researchers said their system underestimated the strength of the quake, initially registering ground shaking at only 4.5 to 4.9 magnitude, far below the actual 7.8 magnitude confirmed later.
The system, which relies on data collected from thousands of Android phones, failed to process the intensity quickly enough to trigger full-scale alerts.
The second major earthquake that struck shortly after was also misjudged. Just over 8,000 Take Action alerts were sent, and 4 million “Be Aware” alerts reached devices—still far fewer than needed.
Google’s Response
In the aftermath, Google admitted to flaws in its algorithm and said it has since made improvements. BBC reports that after internal testing and updates, the system was able to send 10 million “Take Action” alerts and 67 million “Be Aware” alerts during later simulations in similar conditions.
The Android Earthquake Alerts System is designed to detect tremors by using data from mobile phones acting as miniature seismometers. When working as intended, it can override “Do Not Disturb” settings and issue loud emergency alerts.
While the technology holds promise, the 2023 earthquake highlights the critical need for accurate detection and rapid alerts—especially in regions where natural disasters strike with little to no warning.
