Licence compatibility
This site carries a donation link and may carry advertising, which makes it a commercial use in licensing terms. Every dataset above therefore permits commercial use with attribution. Datasets that would otherwise be the best available - notably the GEM Global Seismic Hazard Map (CC BY-NC-SA), the SEDAC Natural Disaster Hotspots layers and WorldClim - are excluded for that reason, and the methodology explains what is used instead and what is lost by the substitution.
