Геология
[ редактировать ]
Вулканическое поле Ибусуки находится на восточных краях ат -кальдеры и, по оценкам, содержит 54 км 3 (13 с ИМ) вулканического материала. [ 2 ] Вулканическое поле Ибусуки включает в себя следующие недавние активные вулканы и их вентиляционные отверстия: [ 2 ]

Geothermal
[edit]There are about 800 hot springs within 5 km (3.1 mi) of the sea at the southeastern tip of the Satsuma Peninsula. [5] The relatively recently commissioned Yamagawa Binary Power Station uses local geothermal power to generate up to 4990 kW.[6]
Tectonics
[edit]The north western sector of the zone is limited by the Onkadobira fault scarp which has been interpreted as part of the rim of the Ata Caldera.[7] The volcanism is associated with the subduction of the Philippine Sea Plate under the Eurasian Plate.
Risk
[edit]The field has both tectonic and volcanic risks. With regard to volcanic risks currently the area is in the longest period between eruptions for the last 4000 years.[2] Earthquake swarms that do not appear to be related to the volcanoes have been described.[8] Seismic activation of local faults in the area occurred immediately after the megathrust 2011 Tōhoku earthquake which had its epicenter 1,350 km (840 mi) away.[9]: 1011
