This series includes technical reports prepared by faculty, students and staff who are associated with the John A. Blume Earthquake Engineering Center at Stanford University. While the primary focus of Blume Center is earthquake engineering, many of the reports in this series encompass broader topics in structural engineering and materials, computational mechanics, geomechanics, structural health monitoring, and engineering life-cycle risk assessment. Each report includes acknowledgments of the specific sponsors for the report and underlying research. In addition to providing research support, the Blume Center provides administrative support for maintaining and disseminating the technical reports.

When planning the design of a structure or a facility in a region of potential seismic activity, it becomes necessary to estimate the ground motion intensity to which the structure will be exposed during its economic life. The required information on the site intensity has to be derived using the seismic information available for the region, such as frequency of occurrence of earthquakes, Richter magnitude levels, etc. Seismic Hazard Models are utilized to obtain the probabilities of the different ground intensity levels at a site. Therefore, the use of an established methodology to perform seismic hazard analysis and hence to synthesize the available seismological information for the purpose of obtaining a reliable estimate of future seismic loading at a site is necessary. The principal objective of the current work is that of describing a set of computer programs organized in a consistent way in order to be used to perform seismic hazard analysis at a specified geographic location. The programs have been developed at Stanford University. They are based on probabilistic seismic risk models discussed in detail by Shah, Mortgat, and Kiremidjian (1975), and Mortgat (1978). They have been utilized for hazard mapping of Nicaragua, Costa Rica, Guatemala, Algeria, offshore Alaska, California, and Honduras (currently in progress) (1, 2, 3, 4, 7). The programs constitute a complementary set and are sufficient for the analysis. They are written in FORTRAN IV and have been tested on the Stanford IBM 370/168 computer. Certain programs, such as plotting and mapping routines, are system oriented and can be used only at the Stanford Computer Center.
