the future of contested strategic competitions in the indian ocean the indian ocean has received new attention in recent years because of its economic and strategic importance. the region is seen as a theatre for great power rivalries mainly between the united states, china, and india. in this regard, this paper assesses how the indian ocean region is coping with the challenges of global powers...

The devastating earthquake (and the corresponding tsunami) that struck the Indian Ocean near Sumatra (Indonesia) on 26 December, 2004 was extremely powerful. In the present study, a very high resolution 3D gravity image has been generated over a part of eastern Indian offshore over the Sumatran earthquake region. Four latitudinal gravity profiles have been generated across the epicenter/aftersh...

This paper deals with the physical and environmental effects resulting from oceanic impacts by sizable comets, and the rates and risks associated with such cosmic impacts. Specifically, we investigate two sets of probable oceanic impact events that occurred within the last 5,000 years, one in the Indian Ocean about 2800 BC, and the other in the Gulf of Carpentaria (Australia) about AD 536. If v...

S U M M A R Y We evaluate far-field tsunami hazard in the Indian Ocean Basin based on hydrodynamic simulations of ten case studies of possible mega earthquakes at the major seismic zones surrounding the basin. They represent worst-case scenarios of seismic rupture along the full extent of seismogenic faults having supported large earthquakes in the historical record. In a series of numerical ex...

Known from time immemorial to the inhabitants of the Pacific region, tsunamis became worldwide known with the great Indian Ocean disaster of December 26, 2004, and its toll of about 234'000 deaths, 14'000 missing and over 2,000,000 displaced persons. Beyond triggering the international help in managing the immediate post-event, and sustaining eventual rehabilitation of about 10'000 km2 of hit c...

A tsunami warning system based on active database system with satellite derived real-time data of tidal, significant wave height and ocean wind speed as well as assimilation data of sea level changes as one of the global risk management systems is proposed. Also, Geographic Information System (GIS) with free open source software of PostGIS is proposed for active database system. It may be said ...
