IEDA / DECADE Detail

Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Harunasan

Haruna volcano is truncated by a small summit caldera containing the symmetrical post-caldera cone of Haruna-Fuji (right). Viscous lava flows and lava domes were extruded within and around the caldera. Its western side is currently filled by Lake Haruna, which is visible to the left of Haruna-Fuji. The Futatsu-dake lava dome, outside the caldera to the east, was the source of two large explosive eruptions during the 6th century CE. This view from the NE also shows steaming Asama volcano on the distant horizon above Lake Haruna. Photo by Ichio Moriya (Kanazawa University).
