Google has admitted its earthquake early warning system failed to accurately alert people during Türkiye's deadly quake of 2023, SİA informs via BBC.
Ten million people within 98 miles of the epicentre could have been sent Google's highest level alert - giving up to 35 seconds of warning to find safety.
Instead, only 469 "Take Action" warnings were sent out for the first 7.8 magnitude quake.
Google told the BBC half a million people were sent a lower level warning, which is designed for "light shaking", and does not alert users in the same prominent way.
The tech giant previously told the BBC the system had "performed well".
The system works on Android devices, which make up more than 70% of the phones in Türkiye.
More than 55,000 people died when two major earthquakes hit south-east Türkiye on 6 February 2023, more than 100,000 were injured. Many were asleep in buildings that collapsed around them when the tremors hit.
Google's early warning system was in place and live on the day of the quakes – however it underestimated how strong the earthquakes were.
"We continue to improve the system based on what we learn in each earthquake", a Google spokesperson said.
