Research

Utpal research focus is to seismically image the Earth’s internal structure from the earth crust to the mantle along with earthquake hazard. Based on the fine structure of Earth, he is trying to understand the linkage between the physical and chemical properties of Earth material with the earthquake and the tectonics of the region. Additionally, he is also interested in the evolutionary history of the continent and plate dynamics of the ocean lithosphere.

         He used a variety of seismological approaches to understand the structure of different tectonically and seismically active regions, including the Mid Atlantic Ridge, Vietnam, Taiwan, South India, and Kumaon Garhwal Himalaya. Currently his group is trying to understand the evolution history of Himalaya based on multiple and advanced geophysical approaches. Additionally his group recently started to work on Earthquake Early Warning (EEW) system. For better reliability and understanding of structure, he always prefers multiple geophysical approaches rather than using a single approach. These includes Seismotectonics and Earthquake Mechanics; Sediment Structure (Using compliance); Receiver Function; Joint Inversion (Receiver Function with Ambient Noise data (or surface wave data)); Finite frequency body wave tomography; Crust and Mantle Anisotropy; Mantle Transition Zone (MTZ; 410 and 660 km discontinuity); Seismic Tomography; Body and Surface wave attenuation, and Earthquake Early warning system.
