Earthquake-detection app captured nearly 400 temblors worldwide

The Android app harnesses a smartphone’s motion detectors to measure earthquake ground motion, then sends that data back to the Berkeley Seismological Laboratory for analysis. The eventual goal is to send early-warning alerts to users a bit farther from ground zero, giving them seconds to a minute of warning that the ground will start shaking. That’s enough time to take cover or switch off equipment that might be damaged in a quake.

 

To date, nearly 220,000 people have downloaded the app, and at any one time, between 8,000 and 10,000 phones are active — turned on, lying on a horizontal surface and connected to a wi-fi network — and thus primed to respond.
