Quake Alarm for Houses
Researchers at NIT, Jalandhar, India have constructed an earthquake alarm which can offer the precious few seconds to save a life when an earthquake strikes. The patent for the invention is ready for grant. The alarm, a simple audio-visual device, when available can be put on the wall of the house and can sense primary vibrations of an earthquake when the P wave (primary) strikes, which is before the actual tremors can be felt. One can run out of the building before collapse in the precious seconds provided by the alarm in case of an earthquake. The alarm gives instant warning of seismic activity by detecting the P (primary) wave, which is weak and starts from epicentre or the compression wave of an earthquake which travels 20 times the speed of sound in air. It is thus 10 times faster than the more destructive S wave (secondary). Simple and low cost, it can be adjusted manually in areas near railway line or a mining area. It looks like a small box which is at present made of wood and runs on rechargeable general purpose battery. The patent has been financed by Punjab State Council for Sciences and Technology, Chandigarh and Technology Information Forecasting and Assessment Council (TIFAC), New Delhi.
