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 ...
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 ...
