Google Admits Earthquake Alert System Failed to Warn Millions During 2023 Turkey Quake.
Google has acknowledged a critical failure in its earthquake early warning system during the devastating 7.8 magnitude earthquake that struck Turkey in 2023.
Despite an estimated 10 million people living within 160 kilometers (roughly 98 miles) of the epicentre — well within range to receive Google’s highest-tier alert, which can offer up to 35 seconds of advance warning — only 469 “Take Action” alerts were issued for the initial quake.
In a statement to the BBC, Google confirmed the shortfall, explaining that approximately 500,000 people received a lower-tier notification meant to indicate “light shaking.” This level of warning is delivered less prominently on Android devices and does not trigger an urgent alert tone or vibration.
The company has not detailed the technical cause of the failure but acknowledged the gap in service and said it is reviewing its systems to prevent similar issues in the future.
The missed alerts have raised concerns over the reliability of early warning technologies in high-risk regions, especially given the scale of destruction and loss of life during the 2023 Turkey-Syria earthquakes.
