This dataset includes hazard data from 10 different cities (Istanbul, Nablus, Chattogram, Cox's Bazaar, Nairobi, Nakuru, Quito, Kokhana, Rapti and Darussalam), to be used in multi-hazard impact modelling. Each dataset represents the hazardscape of the case study area within the cities mentioned above for earthquake, flood, landslide, and debris flow scenarios. The produced hazard maps are simulations that reflect a "what-if" scenario, and not every city contains all hazard type scenarios. The data includes: Earthquake data: Data representing a potential earthquake hazard sourced from a seismic event, that may effect the study area. The intensity measure is either VS30 or SA for the simulated event. Flood data: Data representing a potential flood event due to heavy rainfall event or riverine. The intensity measure is flood depth (height). Landslide / debris flow data: Data representing a potential landslide or debris flow event that is triggered due to heavy rainfall. Hazard parameter files: This file (in .pdf format) provides information on the background of the each hazard scenario such as the location of the source, attributes included and approach that is used (if available) to create it. This dataset was created as part of case studies for the Tomorrows Cities: Tomorrowville virtual testbed. It is supported by NERC as part of the GCRF Urban Disaster Risk Hub (NE/S009000/1) Full details about this dataset can be found at https://doi.org/10.5285/dd5c8a28-a82a-4b73-981c-dd1ead32df26
