Prantik Mandal is a Principal Scientist in the National Geophysical Research Institute (NGRI), Hyderabad, India. He had his education at the Indian School of Mines, Dhanbad, obtaining an M.S. (tech) degree, and at the Osmania University, Hyderabad, obtaining a Ph.D. degree. In his doctoral research work at NGRI, he modeled the intraplate stresses induced by topography, crustal density heterogeneities, and an in-plane compression and shown that these stresses are playing a key role in controlling the occurrences of moderate-size intraplate earthquakes in the Peninsular India. After receiving his Ph.D. degree, he joined NGRI as a Scientist in 1994. Since then, he has focused his research interests on observational seismology and intraplate earthquakes. His work in the field of triggered earthquakes in Koyna-Warna has led to a nucleation model for moderate earthquakes wherein the ruptures nucleate at top 3 km and propagate downward, leading to larger shock. His high-resolution studies in the Bhuj Earthquake region identify the fluid-filled mafic intrusives as stress accentuators that generate crustal earthquakes while the uninterrupted occurrence of aftershocks are triggered by stress-transfer and fluid or volatile CO2 flow mechanisms. This model gets further support from the coincidence of area of crustal (3–7 km) and astheonspheric (6–12 km) thinning, and aftershock activity, as observed through receiver function modeling and relocation of aftershocks. Delineation of seismic sources, site amplification, and sediment thickness maps in concert with attenuation models forms the key inputs for estimating seismic hazard of the region. He has published 64 research papers in International referred journals and 80 abstracts in national and international conferences. Toward the reorganization of his scientific achievements, he has been awarded the Indian Government National Mineral award (Disaster Management, 2007).
