4.     Broad area of Research Seismology                              4.1 Sub Area                   Hydro-seismicity, Radon precursors                                           5.     Approved Objectives of the Proposal :   1. Soil gas and groundwater radon as precursor to seismicity. 2. Hydrochemical evaluation of groundwater and surface water in space and time for study of hydroseismicity and inter communication between them. 3. Identification of groundwater flow paths and linkage between the surface reservoir and ground water using stable isotopes and radiocarbon dating
Date of Start:      September 2004
Date of completion:   October 2009

6.     Methodology :   Identification of intercommunication between surface reservoirs and groundwater (bore well water) by isotopic (radiocarbon dating and stable isotopes) and hydrochemical data. Identification of groundwater flow direction and elucidating relation between flow direction and seismicity. Continuous monitoring of radon in soil gas and groundwater to understand the radon as a precursor to seismicity.
