This study examined the relationships between topographic structure and submarine geomorphology, sediment thickness, geophysical anomaly fields, geological settings tectonic lineament stretching of Arabian Sea region, Carlsberg Ridge morphology, Makran Trench depths by GMT. The included spatial analysis high-resolution datasets (GEBCO, EGM96, GlobSed) geomorphological modeling 300km-width cross...

Great earthquakes rarely occur within active accretionary prisms, despite the intense long-term deformation associated with the formation of these geologic structures. This paucity of earthquakes is often attributed to partitioning of deformation across multiple structures as well as aseismic deformation within and at the base of the prism (Davis et al., 1983). We use teleseismic data and satel...

Tsunami is a system of ocean gravity waves formed as a result of large-scale disturbance of the sea floor that occurs in a relatively short duration of time. The Indian Ocean is likely to be affected by tsunamis generated mainly by earthquakes from the two potential source regions, the Andaman-Nicobar-Sumatra Island Arc and the Makran Subduction Zone. A state-of-the-art warning centre has been ...

Tsunamis are unpredictable events and catastrophic in their potential for destruction of human lives economy. The unpredictability occurrence poses a challenge to the tsunami community, as it is difficult obtain from tsunamigenic records estimates recurrence rates severity. Accurate efficient mathematical/computational modeling thus called upon provide forecasts hazard assessments. Compounding ...

Some subduction zones in nature show mainly overriding plate (OP) extension and low topography, others shortening elevated topography. Here we investigate how end-member modes (trench retreat with slab rollback trench advance rollover) affect deformation (OPD), topography mantle flow time-evolving three-dimensional fully-dynamic analog models using particle image velocimetry (PIV). We conduct t...
