The only known historic eruption was in the first half of the 19th century. Background:from: Smithsonian / GVP volcano informationTwo peaks, Higashimine on the east and Nishimine on the west, form the andesitic volcano. The 495-m-high 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 wide submarine caldera, with Yokoate-jima and Kannone-jima (NNE of Yokoate-jima) being post-caldera cones (Nakano et al., 2001-). Yokoate-sho (Yokoate Reef) and Kannone Kaikyu (Kannone Knoll) lie to NNW and NE of Yokoate-jima, respectively. Historical documents at the end of the Edo Period mention ash plumes from Yokoate-jima.
