When seconds count the Quake Alarm is there for you. This alarm is designed to provide instant warning of seismic activity by detecting the actual "P" wave of the earthquake.
Detects earthquakes many miles away and also monitors aftershocks. Operates off of a 9 volt battery (not included). The Quake Alarm consistently outperformed research and development tests.
