Abstract:

A seismic hazards data base has been developed as a research tool for the engineering and seismology communities. The data base, which is still growing, currently contains information pertinent to a typical seismic hazards investigation: global strong-motion data, U.S. Modified-Mercalli intensity data, historical and instrumental earthquake catalogs, Eastern U.S. strong motion stations, and geotechnical borings (e.g. for New York city) to help in microzonation efforts. The data base is constructed using a relational architecture in which data are stored in tables and are interrelated by key fields. Two interfaces have been designed to make access to the data easy; 1) a single-relation, geographic, interactive graphical data base interface tool (GEOBASE) and 2) a many-relation, menu driven SQL (Structured Query Language) data base interface (DBTOOL).
