| Davuluri Srinagesh had worked at CSIR-NGRI for about 33 Years as a Research Scientist in Seismology. He is credited for designing and operationalising several seismological networks comprising broadband seismological stations, 250 in number namely in the Koyna-Warna region, Indo Gangetic plains, eastern Dharwar craton, NE India, and NW Himalayas in the state of Uttarakhand. The primary objective of these networks is to map the seismically active faults both in the inter-plate and intra-plate scenario and further understand the seismogenesis processes. The seismicity and focal mechanisms have helped in understanding the seismic tectonics of the region and provided the necessary input for assessing earthquake hazard for the siting of critical and vital installations such as Nuclear Power stations, Bridges, and dams. The Indo-Gangetic plains network helped in the determination of sedimentary thickness, responsible for amplifying ground motion due to earthquakes in Himalaya, and resulted in proposing the first ground motion prediction equation of this region. The above study played a significant role in the revised seismic zoning Map of India IS 1893. The current research focuses on the causes of several earthquake swarms in south India. In the initial years of his career, he worked on 3-D tomography of the earth's crust and mantle in south India and provided the first 3-D tomography of the seismogenic volume of the Koyna Warna region for the first time in India. The teleseismic earthquakes helped in mapping the lithosphere structure and mantle anisotropy of the Indian Plate. The seismological stations were set up in the school premises which are remotely located providing an opportunity to undertake outreach programs on earthquake safety to school children in regions of Seismic Zones 4 and 5. Handled Projects both from Government and Industry sponsored for furthering seismological Research |
