3-D seismic velocity structure of the Kumaun-Garhwal (Central) Himalaya: insight into the Main Himalayan Thrust and earthquake occurrence
Gupta, Sandeep; Mahesh, P.; Kanna, N.; Sivaram, K.; Ajay, P. (Oxford Academic, 2022)Objective assessment of seismic hazard and understanding of the Himalayan arc's tectonics requires detailed information on the crustal structure and geometry of the underthrusting Indian Plate beneath the Himalaya. Here, ... -
Caldera-like features located over the Panikkar Seamount and adjacent regions in the Laxmi Basin, eastern Arabian Sea
Savio, J.J.; Yatheesh, V.; Sheldon, R.; Kallathian, M.; Kessarkar, P.M.; Kumar, Kuldeep; Mahesh, P.; Mishra, Subhashree; Verma, Swati (Springer, 2022)The Laxmi Basin, which is believed to have been formed by the divergence between India and the Laxmi Ridge, contains a seamount chain consisting of the Raman Seamount, Panikkar Seamount and the Wadia Guyot in its axial ... -
Gas migration signatures over the volcanic cratered seamount, off the Nicobar Islands in the Andaman Sea
Sriram, G.; Dewangan, P.; Yatheesh, V.; Peketi, A.; Mahesh, P.; Mazumdar, A.; Mahale, V.; Jacob, J.; Dubey, K.M.; Kumar, Pankaj; Mishra, C.K.; Gautham, S.; Anirudh, A.K.; Ankush, P.; MadhavRam, A.B.; Shijin, K.K.; Salkar, T.G.; Zatale, Anjali; Rajurkar, V.; Khokher, S.H.; Garg, Shriya; Choudhary, A.K.; Aswini, K.K.; Gawas, Amol (Springer, 2023)The submarine volcanic arc off-Nicobar is seismologically very active with numerous earthquake swarms reported after the tsunamigenic 26th December 2004 earthquake in the Andaman-Nicobar-Sumatra subduction zone. Therefore, ... -
Magnetotellurics evidence of trapped fluids beneath the seismogenic zone of Anjar earthquake (Mw6.0), Kachchh intraplate region, northwest India
Nagar, Mehul; Pavankumar.G.; Mahesh, P.; Rakesh, N.; Chouhan, A.K.; Nagarjun, D.; Chopra, Sumer; RaviKumar, M. (Elsevier, 2021)Lithospheric rheological heterogeneities across a rift play a significant role in intraplate deformation and seismic activity. The Kachchh rift in the northwestern part of the India has not only experienced lithospheric ... -
Scattered wave imaging of the Main Himalayan Thrust and mid-crustal ramp beneath the Arunachal Himalaya and its relation to seismicity
Mangalampalli, R.K.; Bommoju, P.R.; Mahesh, P.; Venkatesh, Vempati (Elsevier, 2022)Despite numerous seismological experiments in the Himalaya, the Main Himalayan Thrust and the mid-crustal ramp, that is postulated to host major earthquakes in the region, are not precisely imaged.Within the Himalaya, the ... -
Seismotectonics and 3-D seismic velocity structure of the Arunachal Himalaya
Mahesh, P.; Srijayanthi, G.; RaviKumar, M. (Elsevier, 2023)Knowledge of seimotectonics of Arunachal Himalaya holds the key to comprehend the complex deformation scenario in the eastern Himalayan syntaxial (EHS) zone comprising India, Eurasia and Burma plates. Data from a network ... -
The 2005 volcano-tectonic earthquake swarm in the Andaman Sea: Triggered by the 2004 great Sumatra-Andaman earthquake
Kundu, B.; Legrand, D.; Gahalaut, K.; Gahalaut, V.K.; Mahesh, P.; KameshRaju, K.A.; Catherine, J.K.; Ambikapthy, A.; Chadha, R.K. (American Geophysical Union, 2012)A 6 day duration earthquakes swarm occurred in the Andaman Sea, 31 days after the giant 2004 Sumatra-Andaman earthquake (Mw 9.2). The swarm occurred less than 100 km from the eastern edge of the 2004 earthquake rupture and ...
