Abstract
The present study analyzes the 2D scalar wave propagation problems in a time domain BEM through large and complex geophysical structures. To achieve this, a time domain BEM formulation is extended to multi-layered geophysical structures. Using appropriate temporal variations for the field variables the time-related kernels are obtained explicitly. The BEM solutions presented for layered media are generated using synthetic seismograms and are seen to be stable. The seismograms obtained in terms of the BEM and FDM are compared.
