Myoko is located in west-central Honshu and it has a 3-km-wide caldera that is partially filled by a lava dome that forms the highest point. Several edifice collapse events at Myoko have produced major debris avalanches that traveled to the E and NE. The latest dated eruptions of Myoko occurred during the mid Holocene.
