Prior to the occurrence of natural calamities on earth, it has been observed that large variations occur in ambient temperature. In spite of the large amount of research work going on worldwide, methodology and instrumentation for accurate prediction of natural calamities (even a few hours before their occurrence) has remained elusive. In this paper we have developed an instrumentation system that detects increase in seismic activity and in turn helps us to predict the occurrence of the natural calamity well in advance. Large variations in temperature occur much before and during such times. We have used a Quartz based Temperature Sensor to monitor this parameters associated with increased seismicity. The Quartz Crystal HTS-206 is embedded 25meters deep in the ground to detect the variations in temperature. The data is logged ,analysed and further transmitted by using GPRS network on to the Internet through the GPRS Intelligent Modem.
