Google Earthquake Alerts Underperformed in Turkey

System issued fewer high-level warnings than anticipated

Google’s earthquake alert system failed to reach millions of people in Turkey during devastating February 2023 quakes, despite its potential to warn 10 million individuals within a 157-kilometer radius of the epicenter.

Limited High-Level Alerts Issued

For the initial 7.8 magnitude earthquake, a powerful tremor capable of widespread destruction, a mere 469 high-level warnings were dispatched. This number starkly contrasts with the system’s capacity, leaving many with less than 35 seconds to seek safety.

Underestimation of Quake Intensity

Google acknowledged that the system underestimated the force of the earthquakes. While a Google spokesperson described the system as having “worked well,” data suggests a significant underperformance in its primary function.

Additionally, half a million people received lower-level alerts, intended for less intense seismic activity. The system’s underestimation of the earthquake’s magnitude meant these warnings were less impactful.

Android System Reach and Improvement

The alert system operates on Android devices, which power over 70 percent of phones in Turkey. A Google representative stated, We continue to improve the system based on what we learn during every earthquake.

The catastrophic earthquakes on February 6, 2023, claimed over 55,000 lives and injured more than 100,000 people. Many victims were trapped in collapsed buildings as the earth shook violently.

Disaster Preparedness in a Digital Age

The effectiveness of digital warning systems is crucial in disaster management. For instance, Japan’s Earthquake Early Warning system successfully provides seconds of advance notice for many, enabling immediate protective actions, showcasing the potential impact of well-tuned systems. According to the Japan Meteorological Agency, this system aims to issue warnings even for magnitudes exceeding 7.0. This highlights the disparity in performance observed in Turkey.
