About the data

JRC set up an automatic routine that includes the Tropical Cyclone (TC) bulletins produced by the National Oceanic and Atmospheric Administration (NOAA) and the Joint Typhoon Warning Center (JTWC) into a single database, covering all TC basins.

JRC calculates areas affected by high winds (wind buffers at 39, 58 and 74mph). This is done using the maximum reported wind radius (maximum of 4 quadrants) or, in case no wind radii are provided, through a regression analysis based on historical data. JRC also calculates the area affected by storm surge using HyFlux2 (hydrodynamic software).

Sources for data on critical infrastructure are: JRC NUMAS database (nuclear plants), ESRI (hydro dams, 1996), Global Discovery (airports, ports and cities).

Population data is from LandScan 2014.
