History of Mount Hakone

The geological History of Mount Hakone, has been researched by Dr. Hisashi Kuno et al., with Mount Hakone, located in Hakone, Kanagawa, Japan, as a volcano from the Quaternary period.

The current geological map of Mount Hakone, located in Kanagawa, Japan, near Mount Fuji, shows: the "Central volcanic cones" and Lake Ashi in the center, surrounded by the "Old outer rim" on the northeast, north and west sides, and by the "New outer rim" on the southeast side.

Mount Hakone started about 500,000 years ago with the eruptions, that created Mount Kintoki and Mount Myōjō on the current "Old outer rim"; and the subsequent eruptions about 160,000 years ago made the "New outer rim", on which are Mount Sengen and Mount Takanosu (Kanagawa).

From 50,000 years ago, new eruptions further created in the "Central volcanic cones" Mount Kami (35.233333°N 139.020556°E / 35.233333; 139.020556), the highest peak in Hakone, Mount Koma and other peaks; and about 300,000 years ago, the lava domes such as Mount Futago emerged.

Later about 3,000 years ago, the phreatic eruption on the northwest side of Mount Kami caused landslides, creating the Owakudani and, in the huge caldera, the Sengokuhara and Lake Ashi.[1][2]
