Esan - Esan

Japanese: 恵山 - えさん

A double volcano (→ composite volcano) located on the eastern end of the Kameda Peninsula in southwestern Hokkaido. It is an active volcano that is constantly under observation. It is 618m above sea level. It is located at the eastern end of Hakodate City. It belongs to the Nasu volcanic belt, and its outer rim is 350-400m above sea level, with a crater floor 2km in diameter. The central cone, Esan, is located on the eastern edge of the crater floor, and is an andesitic lava dome (bell-shaped volcano) with an elliptical crater ^500m in diameter at its summit. Destruction has progressed on the west side, and sulfur erupts from numerous sulfur vents. The crater floor is called "Goten" and has an area of 34,000m2 and an elevation of 300-400m. An eruption in 1846 caused volcanic mudflows, resulting in many deaths. It is home to a colony of alpine plants such as azaleas, dwarf rhododendrons, black crows, and rock pines. There are also many hot springs, and the mountainside is known as a ski resort. It is close to scenic spots such as Hiura Beach and Cape Esan, and is the center of Esan Prefectural Natural Park.
