How does it work?

 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 than and arrives prior to the more destructive "S" wave (shear wave) and surface waves.   

 

 

When an earthquake occurs, it releases energy in the form of seismic waves that radiate from the earthquake source in all directions. The different types of energy waves shake the ground in different ways and also travel through the earth at different velocities.

The fastest wave, and therefore the first to arrive at a given location, is called the P wave. The P wave, or compressional wave, alternately compresses and expands material in the same direction it is traveling. The S wave is slower than the P wave and arrives next, shaking the ground up and down and back and forth perpendicular to the direction it is traveling. Surface waves follow the P and S waves.  The Quake Alarm™ is sensitive enough to detect the P waves and sound the alarm before the destructive S waves hit.

 Advantage:1.saves valuable seconds by removing the guesswork in earthquake detection.  2.detecting large earthquakes that occur hundreds of miles away  3.can detect moderate to minor earthquakes for many miles around your local area.  4.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.  The human mind relies upon the sensations from the inner ear combined with the sense of sight to determine the sensation of motion the body is undergoing at the time that an earthquake starts.  Disorientation, known as vertigo, can cause people to become confused and instinctively freeze for many seconds during the onset of an earthquake. Sound also plays a part in earthquake detection and by itself can be misleading. The sound of a slamming garage door or the low rumble of a large truck has startled many people into falsely thinking that they are about to experience an earthquake. The Quake Alarm can eliminate confusion, save valuable seconds and provide peace of mind.
