Project Motion Studies Control Center

Department of Science and Technology (DST), Government of India sanctioned a project entitled “National Strong Motion Instrumentation Project” in February 2004 to Indian Institute of Technology Roorkee (IITR). Under this project 294 strong motion accelerographs have been installed in North and NE India covering seismic zones V, IV and some thickly populated cities of seismic zone III. Installations have been done in states of Himachal Pradesh, Punjab, Haryana, Rajasthan, Uttarakhand, Uttar Pradesh, Bihar, Sikkim, West Bengal, Meghalaya, Arunachal Pradesh, Mizoram, Assam and Andaman & Nicobar Islands. Most of these installations have been made in district headquarters inside NIC complex. This network was further strengthened when Ministry of Earth Sciences (MoES), Government of India sanctioned a project entitled “Strong ground motion studies and its applications” in April 2011 to IITR. Under this project strong motion accelerographs installed in North and NE India were proposed to be maintained.  245 of these installations are connected for remote interrogation (from Roorkee) for health monitoring of instruments and data downloading using NICNET of National Informatics System (NIC) and State Wide Area Network (SWAN) of various states. For connectivity between NIC headquarter at Delhi and Roorkee, we have hired a 2 MBPS leased line from BSNL. 20 strong motion accelerographs (12 Kinemetrics and 8 Geosig) installed in Delhi are connected to Roorkee through mobile network.

From this network wealth of strong motion data is getting available, which are being used at National and International level by engineers and scientists. The successful working of this network has laid foundation for Earthquake Early Warning (EEW) system in India. The IIT network is planning to connect more stations, particularly strong-motion accelerograph stations, to the online network, so that a reliable EEW can be developed. IITR is also planning to make some of the stations real time, so that near shake maps can be developed.
