Field notes

The method assigns severity using thresholds adapted from Bowker & Chambers, with “very severe” including 20 or more deaths, one million cubic metres, or a 20-kilometre reach. Ore is classified by the first metal cited, and coordinates are manually assigned at city, district, or regional level. The page names WISE Uranium Project and CSP2 as data sources and Natural Earth for the map; it says candidate events are checked by a person before inclusion.
