Linear elastic boundary element models are commonly used tools to understand the mechanics of earthquake cycle processes and their contribution growth tectonic structures. Here we describe a two-dimensional plane strain linear approach based on displacement discontinuity method. This integrates an analytic solution for coincident interactions using three node quadratic elements classic particul...

We investigate the feedbacks between surface processes and tectonics in an extensional setting by coupling a 2-D geodynamical model with a landscape evolution law. Focusing on the evolution of a single normal fault, we show that surface processes significantly enhance the amount of horizontal extension a fault can accommodate before being abandoned in favor of a new fault. In simulations with v...

In Summer 1998, a 400 km long seismic refraction profile (INDEPTH III) was shot in Central Tibet. Apart from recording the signals of 11 shots along the line, the stations also recorded a number of local earthquakes more or less in the extension of the line. Record sections and travel time data from both shots and earthquakes were compiled and interpreted jointly. The following peculiarities ar...
