Volcano Unzen

Nel 1792 un terremoto fece crollare in mare la cupola del Mayuyama, sollevando uno tsunami che uccise circa 15.000 persone: il peggior disastro vulcanico del Giappone. L'eruzione del 1990–1995 fece crescere la cupola di lava Heisei-shinzan e il 3 giugno 1991 un flusso piroclastico uccise 43 persone, tra cui i vulcanologi Katia e Maurice Krafft.
