Earthquake Preparedness Information Provided to Winnebago County

NEHRP soil types superimposed over the bedrock elevation map for Winnebago County.ISGS engineering geologists produced a report and several maps for consultants to Winnebago County to use for their county hazard mitigation plan. Using existing maps of thickness of materials resting on bedrock and the layers of materials present, the geologists produced a map that indicated how much these materials will amplify earthquake ground motions. This map was specifically designed to be used in a computer loss estimation program that will provide estimates for damage to buildings and infrastructure from earthquakes. The report outlined the techniques used to generate the map.
