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.

Haruna volcano has an irregular profile as seen from an archaeological site to the ENE. The high peak at the left center is Futatsu-dake lava dome, the source of two large explosive eruptions during the 5th and 6th centuries. Tephra layers from both Haruna and Asama volcanoes buried structures at the archaeological site.

The summit of Haruna volcano, seen here from near Maebashi City, SE of the volcano, has a very irregular profile. The volcano is truncated by a caldera and modified by the emplacement of many post-caldera lava domes inside the caldera and on its rim and flanks. Futatsu-dake, the high peak at the right, was the source of two major explosive eruptions from Haruna during the 5th and 6th centuries. These were the last eruptions from Haruna.

The symmetrical cone of Haruna-Fuji is one of many Japanese volcanoes named after the country's most renowned landmark. Haruna-Fuji, a post-caldera cone of Haruna volcano, rises here above Lake Haruna on the western side of the caldera. The Futatsu-dake lava dome to the east was the source of two large explosive eruptions during the 6th century CE.

The irregular profile of Haruna volcano is seen here from the campus of Gunma University in the city of Maebashi, SE of the volcano. A small caldera truncates the summit of Haruna; several post-caldera cones and lava domes produce the volcano's rugged skyline. Two major explosive eruptions during the 6th century CE originated from the Futatsu-dake lava dome on the eastern side of the volcano.
