literature survey on gsm based earthquake detector

Abstract

Humanity is always under the threat of earthquakes. Anatolian peninsula is one of the well-known area which amongst the areas endangered by earthquakes. During the history many dramaticexamples have been occurred. In these earthquakes many people either died or have been injured. In addition, lots of damage in this area has been occurred. More west, in the Sea of Marmara, these earthquakes have also initiated Tsunamis which hit the coastline and caused secondary damages. In this paper GSM-based seismicalert system that could warn before an earthquake strikes.Earthquakes strike without warning. The resulting damage can be minimized and lives can be saved if people living in the earthquake-prone area are already prepared to survive the strike. This requires a warning before strong ground motion from the earthquake arrival. Such a warning system is possible because of energy wave released at the epi center of the earth quake travels slower than light. Thewarningsignal from the earthquake epi center can be transmitted todifferent places using satellite communication network,fiber optics network, pager service, Cell phone services ora combination of these. The satellite-based network is ideal when an alert system has to cover a large country like India. For earthquake-prone states like Gujarat, a seismic alert system using the global system for mobile communication network spread throughout the state isproposed here. This system does not try to find the epicenter or fault line caused by the earthquake. It simply monitors the earth vibrations and generates alert signal when the level of earth vibrations crosses a threshold
