The ShakeAlert Earthquake Early Warning System is a US Geological Survey project that leverages smartphones to detect earthquakes early. The system is based on the fact that GPS receivers in smartphones can detect ground displacement caused by fault motions in large earth quakes.

With ShakeAlert, a network of phones in one area could provide data on the magnitude and distribution of these displacements, before sending alerts to communities that could be affected. Even if only a couple thousand volunteers took part in the program in any given city, the combined data from their phones would suffice to assess the quake.

This venture proves lives can be saved by leveraging the power of the crowd using smartphone technology. This unique earthquake warning system will be useful in less-developed countries.
