We use a finite-difference method on a 3-D staggered grid to simulate seismic wave
propagation in the presence of strong topographic variations. An application to Merapi
volcano, Indonesia, is presented. In order to focus on the effect of topography on the seismic
wave field, calculations are performed for a rather simple model with an isotropic point
source and a homogeneous subsurface medium. Despite this simplicity of the model a
complex wave field evolves. Results of the computation are shown in synthetic …
