I’ve done:
EQs - Haiti, Kobe, Tohoku (Fukushima nuclear plant stuff is good), Boxing Day Tsunami
Volcanoes - Nyriragongo, Montserrat, Eyjafjallajokull (good for economic impacts)
Tropical Storms - Katrina, Nargis (good for complete lack of management and evacuation structure)
Wildfires - North Carolina 2011, Fort McMurray (tbh with wildfires just know a few death tolls to slot in it I find it’s mainly general stuff for this one)
Multi-Hazard - Philippines
??Flooding - Bay of Bengal (in coasts but some good stuff about the mangroves and natural protection)
I also have a few rando interesting ones I know like earthquake retrofitting stuff, volcano prediction stuff, Heimay in Iceland (also interesting for protection side to things), some stuff about avalanches in Pakistan
