Amy Graff, Martín González Gómez
Summary
Google's Earthquake Alerts system, using accelerometers in Android phones, provided early warnings to millions in Venezuela and surrounding countries up to two minutes before back-to-back earthquakes struck on Wednesday. Venezuela lacks its own national early warning system, but Google's system leverages data from over two billion phones to detect seismic vibrations. The alerts gave residents precious seconds to seek safety before the shaking began.
