Smartphones are now part of the global earthquake detection system. The United States Geological Survey (USGS) and Google developed an early warning system using data from seismometers and smartphones. Most smartphones have accelerometers that measure vibrations, which can help detect earthquakes quickly.
The system then sends alerts to apps that can be installed on your phone. One of the apps available for all smartphones is Earthquake Network. The alerts travel faster than earthquake waves, giving people a few seconds to take cover. This technology is important for detecting earthquakes in remote and poorer regions worldwide that don't have seismometers.
