Recent Trends in Prediction of Earthquake

Kaushik K. Ghosh

Abstract: Earthquake is becoming a common natural hazard in Indian subcontinent, especially in extra-peninsular Himalayan region. It has a tremendous destructive power which strikes the earths surface suddenly and sometimes unpredictably. In the present discussion, a generalised idea along with the development of recent state-of- the-art technology related to the prediction of earthquake has been considered. Mitigating earthquake covers from the monitoring of active fault and monitoring of precursory activities like radon discharge from microcracks electromagnetic emissions water level and temperature changes ground uplift and tilt changes in ionospheric parameters etc to the unusual behaviour of animals. A grand success is achieved in the long-term prediction of earthquake. However, short term prediction is yet to be attained.
