At the second URL, the California risk management consulting firm, GeoRisk, provides the first release of its California Earthquake Risk Analysis Web Server. The server is a prototype to a multihazard, multiregional GIS-based Inter/intranet Web server called GeoRAWS (GeoRisk Analysis Web Server). GeoRAWS has three main analysis modules:exposure, hazard, and risk analyses. The exposure module analyzes the geographic and temporal distribution of exposure, based on California's population and building distributions. Exposure is aggregated at various levels of resolution at any given year from 1930 to the present and extrapolated to 2050. The hazard module complements new seismicity maps from the US Geological Survey; it allows Internet users to view California's faults and seismicity and generate hazard maps for any given earthquake scenario using a number of parameters. The loss analysis module (part of the risk analysis module) allows users to estimate dollar losses for any given earthquake scenario in California. Users select a fault from a map and enter the scenario earthquake magnitude, along with other parameters, to determine loss estimates. Dollar losses are aggregated per line of business or occupancy (residential, commercial, industrial, etc.) at any geographic resolution. Inflation and changes in exposure and structural vulnerability over time are incorporated into the models. On-line documentation provides more background information.Questions and comments are welcome and should be e-mailed to info@georisk.com
