Natural hazards: many dormant and some active volcanoes; about 1,500 seismic occurrences (mostly tremors but occasional severe earthquakes) every year; tsunamis; typhoons
volcanism: both Unzen (elev. 1,500 m) and Sakura-jima (elev. 1,117 m), which lies near the densely populated city of Kagoshima, have been deemed "Decade Volcanoes" by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to their explosive history and close proximity to human populations; other notable historically active volcanoes include Asama, Honshu Island's most active volcano, Aso, Bandai, Fuji, Iwo-Jima, Kikai, Kirishima, Komaga-take, Oshima, Suwanosejima, Tokachi, Yake-dake, and Usu
