Geological Survey of India (GSI) launches 22 GPS stations across country

The Geological Survey of India (GSI) has launched 22 permanent Global Positioning System (GPS) stations across India to identify seismically hazardous zones and encourage mapping activities. The 22 GPS-Geodetic (pertaining to Geodesy, the science of earth measurement) observatories are located in Kolkata, Thiruvananthapuram, Jaipur, Pune, Dehradun, Chennai, Jabalpur, Bhubaneswar, Patna, Raipur, Bhopal, Chandigarh, Gandhinagar Vishakhapatnam, Agartala, Itanagar, Mangan, Jammu, Lucknow, Nagpur, Shillong and Little Andaman. These stations are meant to delineate high strain zones for earthquake probability, determine a seismic motion on faults that may lead to a rupture and produce thematic maps with high positional accuracy. The new 13 stations will be located in Aizawl, Faridabad, Uttarkashi, Pithoragarh, Cooch Behar, Zawar, North Andaman, Middle Andaman, South Andaman, Ranchi, Mangalore, Imphal and Chitradurga.
