Physical Risk



A consortium comprised of the Global Earthquake Model Foundation, ImageCat Inc. and the Humanitarian OpenStreetMap Team has been chosen by the Global Facility for Disaster Risk Reduction and Recovery (GFDRR) to develop an open exposure database for multi-hazard risk assessment, as part of the Challenge Funds supported by the Department for International Development of the United Kingdom. This database is capable of storing different assets (building stock, lifelines, infrastructure, crops, forestry, livestock and socio-economic data), while considering relevant attributes for six natural hazards: earthquakes, floods, volcanoes, strong winds, tsunamis and drought. The outcomes of this project were applied to the country of Tanzania to develop an exposure model at the national scale, and to the local level for Zanzibar. This process was also demonstrated for five countries around Tanzania (Ethiopia, Uganda, Kenya, Malawi and Mozambique). This final report summarizes the main outcomes of the four components that comprised this project.
