These data are damage and loss estimates obtained from various Hazus outputs covering all census tracts in 17 counties in and around the San Francisco Bay region in California, for the HayWired earthquake scenario and sixteen M5 or greater aftershocks occurring in the region during the two years following the HayWired mainshock. The HayWired earthquake scenario is a magnitude 7.0 earthquake hypothesized to occur on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. The estimates contained in this dataset are a subset of the many results products generated by FEMA's Hazus-MH 2.1 application, and reflect potential damage due to the HayWired earthquake scenario mainshock and its aftershocks. The data included in this data release were obtained directly from Hazus or by using Hazus outputs to create derivative results. Products include: Hazus building inventory replacement value estimates, Hazus building contents value estimates, estimates of injuries and fatalities (mainshock and three aftershocks), estimates of displaced households and population requiring short-term shelter (mainshock and three aftershocks), value of building damage estimates (mainshock and sum of mainshock and 16 M5 or greater aftershocks), damage ratio estimates (mainshock and sum of mainshock and 16 M5 or greater aftershocks), estimates of damaged square footage by damage state (mainshock), and direct economic losses (mainshock and 16 M5 or greater aftershocks). For additional information on each dataset, please refer to the metadata accompanying the specific dataset of interest. These tab-delimited .TXT datasets were developed and intended for use in standalone spreadsheet or database applications (such as Microsoft Excel or Access). Please note that some data included in this data release are not optimized for use in GIS applications (such as ESRI's ArcGIS software suite) as-is--census tracts are repeated (the data are not "one-to-one"), so not all information belonging to a tract would necessarily be associated with a single record. Separate preparation is needed in a standalone spreadsheet or database application like Microsoft Excel or Microsoft Access before using these data in a GIS.
