지질학적 요약
Takaharayama is a small stratovolcano with lava domes located SW of Nasudake volcano and NNW of Utsunomiya city in central Honshu. The basaltic-to-dacitic volcano lies within the Shiobara caldera, which was formed during the late Pleistocene at the time of the eruption of the Otawara pumice-flow deposit. The latest dated eruption of Takahara took place about 6500 years ago along the NW-SE-trending Yumoto-Shiobara fissure system within the caldera. Eruptions along this fissure initially produced the phreatic Takahara-Uenohara tephra deposit, which was distributed primarily to the east. The symmetrical Fujiyama lava dome, one of many conical volcanoes named after Japan's renowned Mount Fuji, was extruded at the end of the eruption.
Wikipedia 요약
영어 요약Mount Takahara is a stratovolcano in Tochigi Prefecture, Japan. It comprises three volcanic cones, Myojindake, Maekuroyama and Shakagadake, situated within the Shiobara caldera. The caldera-forming eruption occurred in the late Pleistocene. The tallest volcano in the group, Shakagatake, contains four more peaks. Volcanic activity at the present location occurred between 500,000 and 10,000 years ago, and ceased until about 6,500 years ago when a fissure eruption occurred on its northern part. It produced the Takahara-Uenohara tephra deposit, and by the end of the eruption, had formed the Fujiyama lava dome. No eruptions have occurred since, but the volcano has fumaroles and two earthquake swarms occurred during the late 1970s and early 1980s.
