Real Time Seismic Monitoring System for Earthquake Using GPS Technology

Abstract

As part of earthquake process, earth's surface is being deformed as earthquake faults accumulate strain & slip or slowly creep over time. We use GPS to monitor this movement by measuring precise position (within 5mm or less) of stations near active faults relative to each other. In this paper, seismic monitoring is made through a real time analysis using GPS technology. This paper explains how GPS will be used to measure the movement of the earth, i.e., how far the earth actually moved & in what direction, this may be in form of lateral movement or vertical displacement. Here GPS enables direct fault motion measurement in earthquake using one or more GPS's three basic components, i.e. absolute location, relative movement & time transfer. The technology here uses real time GPS information to measure vital stats on a quake. The technology use is referred as, Real Time Earthquake Analysis For Disaster, (READI). Because of its accuracy & precision, the technology has played a vital role in sensing the area precised to 5mm. We here are using the GPS data automatically to calculate the location, magnitude & other details about the earthquake fault. GPS receiver is vital component in are paper because it is stationed to receive the satellite's signal, so that movement could be measured with pinpoint accuracy. It will also measure the high frequency carrier wave used to send the code. Its accuracy is lot higher, providing more precise positional information.
