Subsequent to 2001 devastating Bhuj earthquake of magnitude 7.7, seismicity and earthquake hazard studies in Gujarat are being done at the Institute of Seismological Research (ISR), Gandhinagar. Earthquakes are monitored on 24-hour basis with 60 seismographs (the initiative with auto-location, dissemination and archiving of earthquake information fetched 2013 national e-Governance gold award) and GPS stations across all the faults. Laboratories of ISR include: The Geotechnical Lab which is equipped with all conventional soil testing equipments including Triaxial-Cyclic Testing System, Optically Stimulated Luminescence (OSL) Lab which has two units of OSL equipment for dating of sediments which determine the dates of prehistoric earthquakes for last 20,000 yr, the Geophysical Survey Labs which have geophysical survey instruments for determining sedimentary thickness, nature of basement and hidden faults as well as layers of the crust. The Geophysical Surveys which are carried out include Magnetotelluric, Transient EM, Resistivity Imaging, Gravity, Magnetic and Ground Penetrating Radar. The Land Survey Instruments include Total Station & RTK-GPS and the Engineering Geophysics Lab has PS-Logging, Shallow Seismics setup and resistivity meter. Besides the fundamental research on Physics of the earthquake process, ISR is carrying out research in 16 branches of seismology by integrating Earthquake Engineering, Geotechnical Engineering, Geology, Geophysics, Remote Sensing, Paleoseismology, Hydrology etc. ISR is carrying out earthquake hazard assessment from macro to micro levels. On macro level it has prepared a Probabilistic Seismic Hazard Assessment map of India which Bureau of Indian Standards will recommend for use of construction industry. It is preparing detailed hazard maps at state level and assessing vulnerability of critical installations in coastal regions of Gujarat. At micro level seismic microzonation is being carried out for cities and Special Investment Regions (SIR). It is advising seismic safety factor for nuclear power plants, dams, sky scrapers clusters, Petrochemical plants and various other Industrial Development hubs along Delhi-Mumbai Industrial Corridor in Gujarat. Most of the studies were so far confined to Gujarat. In future, the Institute plans to extend its activities to other parts of India.
