Abstract

We have developed the SYNSEIS (SYNthetic SEISmogram) tool within the GEON (GEOscience Network) project to enable efficient computations of synthetic seismic waveforms for research and education. SYNSEIS is built as a distributed system to support the calculation of synthetic seismograms in 2D/3D media. The underlying simulation software is a finite difference code, E3D, developed by LLNL (S. Larsen). This code is embedded within the SYNSEIS environment and used by our SYNSEIS tool to simulate seismic waveforms of either earthquakes or explosions at regional distances (
