Computer Programs for Seismic Hazard Analysis, a User Manual (Stanford Seismic Hazard Analysis--STASHA)

摘要

A set of computer programs organized in a consistent manner are described and implemented. The programs are based on probabilistic seismic risk models which have been utilized for hazard mapping of areas throughout the world. Constituting a complementary set sufficient for analysis, they are written in Fortran IV and have been tested on the Stanford IBM 370/168 computer. Program titles are: REPLACE.LETTER.MAGNITUDE; INTENSITY.MAGNITUDE; GENER.MAGNITUDE; PLOT. EPI; REGRESSION.ANALYSIS; ACC.LINE.AREA; SORT.MAGNITUDE; SEISMIC.HAZARD; CONST.PROB; and PLOT.ISO. For each program, the purpose and description, input data, macro flow chart, sample problem, presentation, and comments on the output are included. Sample problems are presented to illustrate and test the programs. The data used corresponds to a hypothetical though a realistic situation. A flow diagram schematically shows the three stages of the present form of seismic hazard analysis used at Stanford University.
