We reference damage to a layer showing Magoon's 1968 map of inundation depth and extent. Hyperlinks were created to connect photos with their locations in present day. Using ArcGIS 10, old aerial photos, tsunami inundation maps, and photographs were georeferenced to produce GIS layers of 'before and after' Crescent City. In this study, we assemble all of the available information from these disparate sources into a GIS framework in order to examine the 1964 Crescent City damage in a systematic way and provide a quantitative framework for others who are modeling tsunami impacts. The Del Norte Historical Society has a large amount of archival material (photographs and eye witness accounts) from the tsunami, much of which has never been thoroughly examined or correlated with other reports. In the aftermath of the tsunami, numerous maps, reports and photographs of the impacts in Crescent City were released, some by engineers and scientists, and much by individuals and the popular press. Twenty-nine blocks of the downtown and harbor areas were inundated and nearly 300 homes and businesses damaged or destroyed. Crescent City, California, 3000 km away from the source region, suffered the greatest damage outside Alaska. The March 1964 Alaska tsunami caused major damage in Alaska and also impacted the west coast of North America. A GIS Representation of 1964 Tsunami Damage in Crescent City, California
