A study led by scientists at the U.S. Geological Survey (USGS) has shown smartphones and other personal electronic devices could be used as early warning systems for large earthquakes.

This technology would be especially useful for regions that cannot afford the high prices of conventional early warning systems. Despite being less accurate than scientific-grade equipment, the GPS (Global Positioning System) receivers in a smartphone can detect the permanent ground movement caused by fault motion in a large earthquake, according to USGS.
