Model of Mt. Hakone

In contrast to the simple, cone-shaped Mt. Fuji, Mt. Hakone consists of a basin-shaped depression surrounded by the outer rim, and is called a caldera volcano. Originally, there were a number of active stratovolcanoes in this region. It is believed that a series of large eruptions caused smaller calderas to form, and that the present Hakone caldera has resulted from the coalescence of these calderas. Subsequent eruptions formed a number of central cones within the caldera. In 2015, an eruption occurred in Owakudani located on the northern slope of Kanmurigatake, one of the central cones, and produced a small amount of volcanic ash.
