The most spectacular example of a plate convergence event on Earth is the motion of the Indian plate towards Eurasia at speeds in excess of 18 cmyr−1 (ref. 1), and the subsequent collision. Continental buoyancy usually stalls subduction shortly after collision, as is seen in most sections of the Alpine–Himalayan chain. However, in the Indian section of this chain, plate velocities were merely r...

[1] The plate motion of India changed dramatically between 50 and 35 Ma, with the rate of convergence between India and Asia dropping from 15 to 4 cm/yr. This change is coincident with the onset of the India-Asia collision, and with a rearrangement of plate boundaries in the Indian Ocean. On the basis of a simple model for the forces exerted upon the edges of the plate and the tractions on the ...

Before its collision with Eurasia1–5, the Indian Plate moved rapidly, at rates exceeding 140mmyr−1 for a period of 20 million years1,3–7. This motion is 50 to 100% faster than the maximum sustained rate of convergence of themain tectonic plates today8. The cause of such high rates of convergence is unclear and not reproduced by numerical models9,10. Here we show that existing geological data11,...

Indian peninsular region comprises several Archean cratonic blocks (Dharwar, Bastar, Singhbhum, Aravalli – Bundelkhand), bordered by Proterozoic mobile belts. Therefore, this region is considered as tectonically stable and designated as the least vulnerable region to earthquake hazard except the still active Central Indian Tectonic Zone (CITZ). The latter is a major suture between southern and ...

In order to understand the potential controls on Asian tectonics during the subduction of the Tethys and Indian lithospheres, we reconstruct the coupled subduction-continent deformation history using tomographic imaging, kinematics constraints and numerical modeling. The global P-waves tomographic images of the mantle below the India-Asia collision zone provide constraints on the deep structure...

Indian Ocean is known as a source of moisture for southeast of Iran due to summer precipitation. In this study, in order to investigate the role of SST of Indian Ocean, and the convergence and divergence fields in the precipitation of southeast of Iran, precipitation data of five synoptic stations were used during 2000-2010, including Iranshahr, Khash, ChahBahar, Zabul, and Saravan. To investig...

Most mountain ranges are flanked by foredeep basins, and in general neither the ranges nor the basins are in local isostatic equilibrium. The basins are overcompensated whereas the ranges themselves are usually undercompensated, I describe a method of analysing gravity anomalies over mountain ranges assuming that the topography is supported by the elastic strength of the continental lithosphere...

In this paper, a smart and simple algorithm is presented for Indian vehicle's license plate recognition system This introductory paper describes the need of Indian license plate detection, recognition system, Indian license plate characters, Structure of Indian License plates, and License Plate image pre-processing methodologies. For extracting the license plate methods and such as to dete...

Analysis of the earth’s longest period normal modes shows that the December 2004 Sumatra–Andaman earthquake was much larger (Mw 9.3) than initially inferred from surface-wave data and involved slip on a much longer fault than initially inferred from body-wave data. The seismic moment and relative excitation of the normal modes indicate that the entire aftershock zone ruptured, consistent with t...
