Prediction is IMD's priority

Any pattern, if found – and that's a big if – could lead to successful earthquake prediction, which is beyond the reach of science now. IMD in association with three other institutes is currently studying earthquake precursors through its observatories in Ghuttu in Himachal Pradesh, Shillong in Meghalaya, Koyna in Maharashtra and Port Blair in Andaman. The studies, however, have not come to the point of real-life earthquake forecast.

“Preliminary analysis of these data have provided useful leads on the ongoing tectonic processes, particularly in the Koyna region,” said R S Dattatreyam, who heads the seismology division at IMD.

The ministry of earth sciences has initiated a programme on the study of earthquake predictors under which scientists are studying precursory phenomenon like gravity anomalies, electrical resistivity changes, electromagnetic perturbations, water level changes, geo-hydrochemical changes, Radon and Helium anomalies and thermal anomalies.
