New Delhi, Mar 6: Contrary to popular perception no increasing trend in the frequency of earthquake has been noticed, says the India Meteorological Department (IMD).

IMD is the nodal agency in the country to monitor earthquake activity on 24X7 basis and notify the magnitude and location soon after the occurrence of any earthquake in and around the country. Statistical analysis of the available earthquakes database does not indicate any apparent increasing trend in the earthquake frequency, the Government told Rajya Sabha in a written reply. With the densification of seismic network in recent times, it has become possible to detect lower magnitude earthquakes over India.

The capability has been augmented recently in the wake of the Tsunami waves that struck the Indian coasts on December 26, 2004. As part of the network augmentation, a Real Time Seismic Monitoring Network (RTSMN) consisting of 17 field stations has been set up with auto-location capability to provide timely input to the Tsunami Warning System in operation at Indian National Centre for Ocean Information Services (INCOIS), Hyderabad.

However, providing information prior to the occurrence is not possible as on today, anywhere in the world as no prediction methodology exists. Global scientific community is making efforts to study the pre-cursory phenomena of earthquakes, said Science and Technology Minister Kapil Sibal.
