Possible Linkages between Microseisms in the Andaman?Nicobar Region and Swells in the South Indian Ocean
(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 ...
Sub-surface magma movement inferred from low-frequency seismic events in the off-Nicobar region, Andaman Sea
(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 ...
Seismotectonic evaluation of off Nicobar earthquake swarms, Andaman Sea
(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 ...
Tidal Triggering of the Harmonic Noise in Ocean-Bottom Seismometers
(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 ...
