Minister of State for Science & Technology and Earth Sciences Shri Y. S. Chowdary in a written reply Rajya Sabha today said that efforts are being made world-over including in India, to monitor and study various earthquake precursory phenomena in critical seismotectonic regions. He sad this would not only help understand the earthquake generation processes better, but also lead to identifying possible earthquake precursors, which may serve as useful predictors in future. As part of this, a Program on 'Seismicity & Earthquake Precursor' has been initiated by Ministry of Earth Sciences (MoES), through a multi-institutional and multi-disciplinary mechanism to adopt an integrated approach of generation, assimilation and analyses of a variety of earthquake precursory phenomena in critical seismotectonic environments in the country. The Ministry of Earth Sciences (MoES) has also initiated a major project on drilling a deep bore hole in the seismically active Koyna-Warna region in Maharashtra, to study in detail the ongoing earthquake generation processes in the region. The proposed scientific deep drilling investigations in the seismically active Koyna region will provide a unique opportunity and the much desired data sets to better understand the mechanisms of faulting, physics of reservoir triggered earthquakes and also contribute towards earthquake hazard assessment and develop models for earthquake forecast in future.
