TEHRAN, Aug. 4 (Mehr News Agency) - Invented in the U.S. in 1995, the Quake Alarm is an inexpensive earthquake detector for homes, offices and school classrooms that sounds a loud buzzer 40 seconds before a quake begins, the equipment importer told the Tehran Times.
Being tested and widely used in Turkey, India, Nepal and Mexico, the Quake Alarm saves valuable seconds by removing guesswork in earthquake detection. 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, he added.
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 importer of the precision equipment explained.
One very important advantage of the set is waking you up and alerting you moments before the quake so that you can immediately take over or tend to other family members, he further said.
