Details for: Izu-Tobu
Snow drapes the western flanks of Omura-yama scoria cone in the Izu-Tobu volcano group. Omuro-yama, the most well-known feature of the Izu-Tobu volcano group (also known as the Higashi-Izu volcano group), formed about 5000 years ago. The volcanic field is scattered over a broad, plateau-like area of more than 400 sq km on the east side of the Izu Peninsula. About 70 subaerial monogenetic volcanoes formed during the last 140,000 years, and chemically similar submarine cones are located offshore.
