Details for: Takaharayama

Forested Fuji-san lava dome, one of many conical volcanoes named after Japan's renowned Mount Fuji, is the youngest product of Takahara volcano. This small stratovolcano with associated lava domes is located SW of Nasu volcano. The latest dated eruption of Takahara took place about 6500 years ago. Eruptions along a NW-SE-trending fissure produced phreatic tephra and were followed by emplacement of the Fuji-san lava dome and a cryptodome (an area of lava intrusion where lava did not reach the surface) on the NW side of the dome.
