Responsibilities I am an Earth scientist with special interests in geodynamics, earthquake geology and tectonics. He contributes to the understanding of the earthquake source zones and fault zones of India, thereby assisting the seismic hazard evaluation. My studies are mostly focused in the areas of active tectonics, earthquake geology, paleoseismology and tectonic geomorphology. To address the key questions in seismology like the seismic gap hypothesis, and characteristic earthquakes (slip-predictable or time predictable models) or spatial and temporal clustering of earthquakes (explained as due to stress triggering and fault interaction) it is important to understand how seismic sources behave in the longer term. Extensive database on spatial and temporal earthquake recurrence patterns for various fault systems helps to draw realistic statistical conclusions. My work is mainly focused on developing insights into earthquake sources, leading to their long-term behavior.

I have contributed to the understanding of the recurrence patterns of major earthquakes/tsunamis and nature of fault zone deformation in various tectonic regimes of India. My research targets to further the knowledge on the earthquake generation along the plate boundary systems like the Himalaya and Andaman-Nicobar tectonic zones as well as the intraplate regions like the failed rift zones like Kachchh, in the northwest India – major potential source of damaging earthquakes. I conduct field investigations of various geological and geomorphological features along with direct observations of fault offsets preserved in the local geology or the indirect indications like soil liquefaction to develop tectonic models of earthquake kinematics. I employ various Quaternary dating techniques and laboratory analyses to constrain the ages of these features. I have also contributed to the understanding of geodynamical aspects of the Andaman subduction zone- the source zone of the 2004 mega-earthquake and the consequent devastating tsunami through the application of global positioning system (GPS) based strain measurements and earthquake seismology. I have also taken a lead role in the collaborative work and international cooperation on tsunami hazard and capacity building as part of initiatives sponsored by Intergovernmental Oceanographic Commission, and has established linkages among various researchers from many Indian Ocean countries from Australia to Iran to understand the transoceanic tsunami hazards.
