We present a large scale finite element simulation of fully elastic seismic waves propagating in a complex three dimensional geological environment. Our results are noteworthy on three accounts: 1. The complexity of the synthetic model which involves a folded structure and variable velocity of propagation. 2. The size and detail of the computational mesh, with over 19 million elements and 1700 time steps. A high computational efficiency and speed of execution. A finite element explicit-in-time

... rocedure was used to solve the 9D elastic wave equations. The wave train was generated b y a 3 Hz surface pressure source over a simulated time interval of 10 seconds. The simulation itself took 4.5 hours t o complete on a Fujitsu VP24OO supercomputer, at a sustained rute of about 0.5 GFLOPS.
