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 ...
Morphotectonic signatures and revised timing of opening of the Andaman Backarc Basin, Northeast Indian Ocean
(Elsevier, 2021)
The Andaman Backarc Basin is believed to have been formed by the present episode of seafloor spreading in the Andaman Sea, separating the Alcock Rise in the north (Burmese Plate) and the Sewell Rise in the south (Sunda ...
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 ...
