Photo Gallery


The dumbbell-shaped island of Yokoate-jima lies at the bottom-center part of this NASA Landsat image (with north to the top). The small, 3.5-km-long Yokoate-jima and Kannone-jima to the north are likely post-caldera cones of a large submarine caldera. Yokoate-jima consists of two volcanic cones forming Nishimine (West Peak) on the left and Highashimine (East Peak ) with its symmetrical summit crater on the right. Historical documents from the end of the Edo Period reported ash plumes from Yokoate-jima.

Nishi-mine, the western peak of Yokoate-jima, is seen from the NW with a road visible at the left that reaches the summit crater. Yokoate-jima is a small, 3.5-km-long, dumbbell-shaped island at the SW end of the Tokara island chain. Two peaks, Higashi-mine on the east and Nishi-mine on the west, form the andesitic island. Yokoate-jima is a post-caldera cone of a 7 x 10 km wide submarine caldera. Historical documents at the end of the Edo Period mention ash plumes from Yokoate-jima.
