Kuruse Hole is a submarine circular caldera located between Mikurajima and Hachijojima in the Izu Islands chain. The caldera is 600-760 deep and 5–7 km wide. A flat-topped rim of a probable somma (pre-caldera cone) rises to within 107 m of the sea surface.
Large amounts of dacitic pumice were recovered from dredges along the inner caldera wall. Kurose caldera seems to be young, based on its morphology, but the age of its most recent eruption is unknown.
Blue flames of burning sulfur: Ijen volcano in East Java has one of the most impressive sulfur deposits on earth. They are so hot that the sulfur often ignites - a mysterious display at night caught on camera.
