Earthquake Network is the most comprehensive app on earthquakes and for most countries of the world it is the only earthquake early warning system able to alert you before the seismic waves.
Main features:
The Earthquake Network research project develops a smartphone-based earthquake early warning system able to detect earthquakes in real time and to alert the population in advance. Smartphones are able to detect earthquakes thanks to the accelerometer on-board each device. When an earthquake is detected, users with the application installed are immediatly alerted. Since earthquake waves travel at a finite speed (from 5 to 10 km/s) it is possible to alert the population not yet reached by the damaging waves of the earthquake.
Note that the information on earthquakes detected by national and international seismic networks is usually published with a delay ranging from a few minutes to many hours, depending on the seismic network.
