Yokoatejima

Stratovolcano · Japan · 495m

Nishimine, the western peak of Yokoatejima, is seen from the NW with a road visible at the left that reaches the summit crater. Yokoatejima is a small, 3.5-km-long island at the SW end of the Tokara island chain with two peaks, Higashimine to the E and Nishimine to the W. It is a post-caldera cone within a 7 x 10 km submarine caldera. Historical documents at the end of the Edo Period mention ash plumes.

Geological summary

Yokoatejima is a small, 3.5-km-long, dumbbell-shaped island NW of Amami Oshima Island at the SW end of the Tokara island chain. Two peaks, Higashimine on the east and Nishimine on the west, form the andesitic island. Higashimine, the high point of the island, has a steep-walled, well-preserved summit crater. An arcuate ridge east of Yokoate-jima appears to be part of 7 x 10 km submarine caldera, with Yokoatejima and Kaminonejima to the NNE being post-caldera cones (Nakano et al., 2001-). Yokoatesho (Yokoate Reef) and Kaminone Kaikyu (Kaminone Knoll) lie to NNW and NE of Yokoatejima, respectively. Historical documents at the end of the Edo Period mention ash plumes from Yokoatejima.
