Maps of strong ground shaking are the basis for earthquake loss estimation and resulting hazard mitigation efforts. Modern Geographic Information Systems (GIS) provide a powerful tool for integrating data on active faults, seismicity, tectonic setting, surficial geology, hydrology, fault rupture characteristics, and ground motion models in preparing such maps. This information from the earth sciences is combined with that from the built environment and the social sciences to infer earthquake losses. A repeat of the Great 1906 San Francisco Earthquake could cause 8,000 deaths and 225 billion dollars in property losses.

This presentation has been prepared to run as an automated slideshow. It contains 41 slides and takes 15 minutes to cycle through. For those with bandwidth concerns the text is 0.2Mb, photos 1.1Mb, other figures 0.5Mb, and sound 7Mb. Sound is not recommended for modem users. Modem users may also find it necessary to click on photos or maps in order to download them before the slideshow advances. Manual controls are provided for moving around within the slideshow and for turning the sound/narration on or off. Moving to the index page will allow the choice of any page in the slideshow. For best results use 24-bit color mode (true color) and full-screen for the browser. The font size should be set to the largest size that still allows the blue control line (sample below) to fit on one line.

Sample control line (Set font size so control line fits in one line.)
