FEM simulation of interseismic and coseismic deformation associated with the 2008 Wenchuan Earthquake

► We model inter- and coseismic deformation associated to the Wenchuan earthquake. ► The inverted optimum model fits the observed data very well. ► High elastic strain energy rate is found in and around the Longmen Shan. ► Modeled coseismic normal and shear stress on the surface of the fault changes. ► These stress changes on the surface of the fault promote the Wenchuan earthquake.
