This picture was taken in the central part of caldera. Although there is a trail to get there from the rim, there is no mark to go back to the trail. It was extremely difficult to find a way. I advise that you should not try to go there, because the mobile phone cannot be usable inside the caldera.
This picture was taken from the helicopter (Tokyo Ai-land Shuttle; on the way to Hachijo airport from Aogashima).
On September 27, 1994, massive landslide occurred in the South-eastern side of Aogashima village. Two persons were killed, and 1 was missing due to this disaster.
Retrieval construction is still performed.
