Most Recent Bulletin Report: October 1992 (BVE 32)

Discolored water with sulfur odor reported by fishing boat

[The following provides additional information about the 7 October 1992 observation.]

"Shira-ne, a small rock mass of two pyroxene andesite 7.7 m below sea level, located about 7.5 km NE of Smith Rocks and about 500 km S of Tokyo, forms an E part of a submarine caldera about 8 km in diameter (figure 1). Smith Rocks, 136 m a.s.l., forming S rim of the caldera are of olivine basalt.

"On October 7, 1992, yellow discolored water smelling sulfur was reported by a fishing boat, Daini-Odamaru, suggesting a submarine volcanic activity. The area of discoloration was 6 km long and 30 m wide."

Small zone of discolored water

A zone of discolored yellowish water 30 m [wide] and [6 km long] was observed by fishing crews at around 1100 on 7 October. A JMSA overflight on 9 October showed no anomaly. The volcano last erupted in 1916, ejecting tephra. Discoloration was seen at the shore and near the island in 1975, 1976, 1977, 1989, and August 1992.
