The exposure data was originally developed by the U.S. Federal Emergency Management Agency’s HAZUS program and has been translated to the OpenQuake engine format by GEM. The exposure model uses the 2010 U.S. Census for residential buildings (U.S. Bureau of the Census, 2010), Dun & Bradstreet (2006) for nonresidential buildings, and R.S. Means (2014) for all building replacement costs. Exposure data is available through FEMA’s Hazus program at the census tract level for population, commercial, industrial and residential buildings.
