About the data

The information on storm characteristics is taken from a web service provided by the Pacific Disaster Center, which processes the official advisory bulletins.

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 2010.
