Mount Esan
Esan (エサン, 恵山)
The volcano Mount Esan
Mount Esan (618.1 m elevation) is a small stratovolcano, and faced to Tsugaru Straits, Hokkaido Island, Japan, and was assigned as Esan Prefectural Natural Park in 1961 when I was born. A minor phreatic eruption in 1846 induced a mudflow. The last (small) eruption took place in 1874. Sulfur buring occurred in 1876 and 1962. Nowadays, fumaroles emerge from the upper northwestern flank.
