Description
- Early earthquake warning device
- Sounds like a smoke detector
The Quake Alarm Earthquake Detector with its patented reverse pendulum detection system gives you precious seconds to respond right when an earthquake is detected. The Quake Alarm is designed to provide instant warning of seismic activity by detecting the P wave (compression wave) of an earthquake which travels faster than the more destructive s wave (shear wave). The P wave can be detected and sound the alarm before people can actually feel the earthquake. The Quake Alarm is capable of detecting large earthquakes that occur hundreds of miles away. It can also detect moderate to minor earthquakes for many miles around your local area. The Quake Alarm buzzer is loud enough to wake you up when asleep, giving you time to immediately take cover or tend to family members.
