Harunasan volcano is seen here from Gunma University in the city of Maebashi to the SE. A small caldera is at the summit along with several cones and lava domes that have formed within it. Two major explosive eruptions originated from the Futatsudake lava dome on the eastern side of the volcano during the 6th century.
