Geology and geography

Mount Myōkō was formed beginning about 300,000 years ago, in a series of eruptions producing a broad spectrum of lava types including basalt, andesite, and dacite. Its maximum height is estimated to have been between 2800m (9,200feet) and 2900m (9,500feet), but it presently reaches only 2454m (8,051feet). Around 19,000 years ago, the top was blown off in a major eruption, forming a 30NaN0 wide caldera. About 6,000 years ago, the central crater developed and assumed its present shape. A lava dome forms the volcano's present summit. The most recent eruptions about 4,300 years ago produced pyroclastic flows down the eastern flanks. Present activity is solfataric from fumaroles near the lava dome where sulfur was once mined.

There are onsen and ski resorts at the foot of the mountain, including Akakura, Suginohara and Ikenotaira.
