SSC Seismology Software Center

The center established under the CzechGeo/EPOS project contains more than 100 open-source computer programs for the public addressing the propagation of seismic waves, together with their hypertext documentation and demo data. The main products are SW3D ray-based software designed for 3-D velocity models and ISOLA software for determining torque tensors. Software development took more than 30 years. The center provides modern software for seismological applications based on ray theory, and has over 130 registered users and an unknown number of unregistered users. It provides approximately 100,000 source code files per year.
