The 6.1 magnitude earthquake that shook Balıkesir and surrounding provinces brought a significant technological advancement, as well as fear, to the forefront of public awareness. Thousands of Android users were surprised by a notification they received on their phones approximately 30 seconds before they felt the tremor. The notification read, “A 5.2 magnitude earthquake is expected nearby.” So, how does this system work?
How does the Android Earthquake Warning System work?
Google’s Android Earthquake Warning System uses motion-detecting accelerometers in smartphones. When the system detects the P wave, the first wave of an earthquake that isn’t destructive, it analyzes data from millions of phones and creates an alert network within seconds. This gives users precious seconds to implement lifesaving reflexes like duck, cover, and hold on before the devastating S wave reaches the area.
The difference between the system’s estimated magnitude (5.2) and AFAD’s official magnitude (6.1) for the Balıkesir earthquake stems from the system’s rapid analysis of P wave data. However, this “minor” error highlighted the potential of technology to provide even seconds’ notice of a disaster and the critical role it can play in the future. This incident has once again proven the vital role of early warning systems in disaster management.
