December 2014: Aso is erupting right now, and to get a better overview on all webcams available I decided to dedicate an entire page to him.



Asosan, central Kyushu. The 24-km-wide caldera has 17 central cones - one of which is Nakadake, one of Japan's most active volcanoes. Basaltic to basaltic-andesite ash emission with periodic strombolian and phreatomagmatic activity. The summit crater of Nakadake is accessible by toll road and cable car, and is a popular tourist destination.

Mt. Nekodake (1,433m) is one of the central cone group in the Aso Caldera (as is the active cone Nakadake), but no eruptions have been reported in historical time.

Mimata-yama    ? Min.    O-Web    O-IMG        
In the NE-ern Aso caldera, Mimata-yama is a dome of Kujusan volcanic complex of stratovolcanoes and lava domes. The group consists of 16 andesitic lava domes, five andesitic stratovolcanoes, and one basaltic cone. The latest magmatic activity occurred about 1600 years ago, but phreatic events have been reported in historical times.
