Three pieces of software in current use for studies of earthquake and fault interaction will be the subject of a two-day hands-on workshop to be held in Palo Alto on September 8-9. The goal is for the participants to develop sufficient skill that they will use the software in their own research and teach its use to others.
The course will introduce participants to Coulomb 1.0, 3D-DEF, and VISCO1D. The applications will be presented by their authors, who will walk participants through tutorials and provide simple manuals. All software and manuals will be available electronically.
To give everyone keyboard/monitor access, the workshop is lim-ited to 45 participants. Housing will be in suites at the Schwab Residential Center of the Stanford Business School. Instruction will take place at the Mitchell Earth Sciences 20-station training center. Participants will arrive on the afternoon of September 7, followed by a welcoming reception that evening. Other events include a barbecue on Wednesday evening and an afternoon run. The work-shop is scheduled to conclude by 6 p.m. on September 9. SCEC will cover tuition, airfare within California, airport van shuttle, meals, and accommodations for its members.
Coulomb 1.0, principally written by Shinji Toda (ERI, Japan)-an evolution of GEN 1.0 by Geof King (IPG, Paris) is a fast, menu driven Mac program rich in graphics that performs 3D elastic dislocation and a limited number of 2D boundary element calculations of deformation and stress in an elastic half-space. Ross Stein will help Shinji Toda teach this session.
3D-DEF, written by Joan Gomberg (USGS, Memphis) and Michael Ellis (CERI, Univ. Memphis), performs elastic dislocation bound-ary- element calculations. The program enables a variety of boundary conditions to be applied, which makes the model quite flexible. The program and manual can be obtained via anonymous FTP to beagle.ceri.memphis.edu in the "/pub/gomberg" directory.
VISCO1D, written by Fred Pollitz (UCD) calculates the response of a spherically stratified elastic-viscoelastic medium to the stresses generated by fault slip or dike opening occurring in one of the elastic layers.
