A brief study on the imprints of seismo tectonic activities in the crust of central and southern Bay of Bengal
Bathymetry, magnetic and shallow seismic data collected north and south off Visakhapatnam revealed the extension of onshore lineaments to offshore. Stability of the area has been studied from the physical properties of sediment samples, bathymetry, magnetic and seismic data, which are collected befo...

Bathymetry, magnetic and shallow seismic data collected north and south off Visakhapatnam revealed the extension of onshore lineaments to offshore. Stability of the area has been studied from the physical properties of sediment samples, bathymetry, magnetic and seismic data, which are collected before and after Great Sumatra Eanhquake (GSE), followed by Tsunami. Detailed analysis of shipborne gravity and satellite gravity data around 12 degrees N latitude indicated isolated gravity lows away from the coast up to 85 degrees E Ridge gravity low.
