Researchers in the U.S. and Germany have tested a global earthquake detection and alert system that makes use of a device many people already own, including in less developed countries—Android smartphones. According to their study, published today in the journal Science, the Android Earthquake Alerts (AEA) system’s efficacy rivaled traditional seismic networks in its ability to detect seismic activity and deliver alerts.

“The global adoption of smartphone technology places sophisticated sensing and alerting capabilities in people’s hands, in both the wealthy and less-wealthy portions of the planet,” the researchers, including Richard Allen from the University of California in Berkeley’s Seismological Laboratory, wrote in the study. “Although the accelerometers in these phones are less sensitive than the permanent instrumentation used in traditional seismic networks, they can still detect the ground motions and building response in hazardous earthquakes.”
