Yokoatejima
The island is formed by two smaller stratovolcanoes - Higashimine (東峰) to the east, with a maximum elevation of 494.8 metres (1,623 ft) and Nishimine (西峰) to the west, with a maximum elevation of 259 metres (850 ft). The only known volcanic activity on either peak was towards the end of the Edo period, around 1835 ± 30 years. The inside of both caldera are forested, whereas the outer slopes of both mountains is largely barren.
