The Quake alarm is designed to provide early warning of seismic activity by detecting the "P" Wave (compression wave) of an earthquake, which travels faster then and arrives prior to the more destructive "S" wave (shear wave).

It Is capable of detecting large earthquakes that occur hundreds of miles away and can detect moderate to minor earthquakes for many miles around your local area.  One very important advantage of the Quake Alarm is that it can wake you up and alert you the moment the quake starts so that you can immediately take cover or tend to other family members.
