Possible Linkages between Microseisms in the Andaman?Nicobar Region and Swells in the South Indian Ocean
Reddy, T.R.; Dewangan, P.; Bhaskaran, P.K.; Roy, P.N.S. (Seismological Society of America, 2021)Microseism source characterization and its genesis play a key role in linking microseism records to prevailing atmospheric and oceanic conditions. In the present study, we analyzed the spatial and temporal distribution of ... -
Seismotectonic evaluation of off Nicobar earthquake swarms, Andaman Sea
Aswini, K.K.; KameshRaju, K.A.; Dewangan, P.; Yatheesh, V.; Singha, P.; Reddy, T.R. (Elsevier, 2021)The Andaman Sea has experienced a number of earthquake swarms as a result of complex tectonics arising from oblique subduction, active volcanic arc, the backarc spreading center, and sliver fault systems. One of the most ... -
Sub-surface magma movement inferred from low-frequency seismic events in the off-Nicobar region, Andaman Sea
Aswini, K.K.; Dewangan, P.; KameshRaju, K.A.; Yatheesh, V.; Singha, P.; Arya, L.; Reddy, T.R. (Nature Publishing Group, 2020)Monitoring volcanic activity along the submarine volcanoes that are usually induced by subsurface magmatism is a challenge. We present fresh set of Ocean Bottom Seismometer (OBS) data that shows geophysical evidence ... -
Tidal Triggering of the Harmonic Noise in Ocean-Bottom Seismometers
Reddy, T.R.; Dewangan, P.; Arya, L.; Singha, P.; KameshRaju, K.A. (Seismological Society of America (SSA), 2020)We observed a harmonic noise (HN) in DEPAS ocean-bottom seismometers (OBSs) data recorded from the Andaman-Nicobar region. The HN is characterized by sharp spectral peaks with a fundamental frequency and several overtones ...
