Coupled subduction dynamics and continent deformations: understanding the Asian and Red Sea tectonics.

We propose to model plate tectonics coupling the dynamics of sinking slabs in Earth s interior and the plate motions and deformations at its surface. We will understand (1) how forces generate and propagate across margins (2) how deformation is taken by plates and (3) how the feedback between the two account for the complexities of Asian collision and Red Sea rifting. Understanding this dynamic interaction allows assessing the earthquakes potential of plate margins, as expressed by the recent devastating events in Indonesia, offering an insight into sedimentary basins and shear zones, where resources as oil and ore deposits are located.
