Geographic Boundaries¶
Administrative Boundaries¶
Administrative units (ADM2, ADM1 and ADM0) are obtained from the World Bank Global Administrative Divisions FeatureServer service, which provides standardized boundary data globally.
Urban Areas¶
In addition to administrative boundaries, ThinkHazard! classifies hazards for approximately 3,000 major urban areas globally (largest cities and chief towns). Urban area boundaries are obtained from the GHSL Urban Centre Database (UCDB R2024A), developed by the Joint Research Centre of the European Commission based on satellite imagery and population data.
Climate Indicators¶
Information about climate indicators is obtained from the Climate Change Knowledge Portal (CCKP) published by World Bank Group and from additional studies.
Hazard Datasets¶
ThinkHazard! integrates global hazard data from multiple authoritative sources:
Floods (Fluvial, pluvial, coastal)¶
Based on global River/Pluvial/Coastal flood hazard maps produced by Fathom (v3). Data are not publicly disclosed due to license terms.
Water Scarcity / Drought¶
Based on global water stress (baseline) hazard maps produced by Aqueduct (v4).
Landslides¶
Based on global Landslide susceptibility index published by UNEP/GIRI (2025). Available for download at Risk Data Library.
Earthquake¶
Based on global Earthquake hazard maps published by GAR (2017).
Tropical Cyclone / Strong Winds¶
Based on global STORM (v4) wind hazard maps published by Bloemendaal N. (2023). Available for download at Risk Data Library.
Volcanic Eruption¶
Based on global Volcanic eruption database published by NOAA (2025).
Extreme Heat¶
Based on global extreme heat maps published by GFDRR-VITO (2025). Available for download at Risk Data Library.
Tsunami¶
