Volcano Unzen
En 1792, un séisme a fait s'effondrer le dôme du Mayuyama dans la mer, soulevant un tsunami qui a tué quelque 15 000 personnes : la pire catastrophe volcanique du Japon. Son éruption de 1990–1995 a fait croître le dôme de lave Heisei-shinzan, et le 3 juin 1991 une coulée pyroclastique a tué 43 personnes, dont les volcanologues Katia et Maurice Krafft.
