Quimsachata (Kimsachata) is the northernmost active volcano in Peru and located at the foot of the Cordillera Oriental in an isolated area far east of the main volcanic front.
It sonsists a group of 2 vents: Quimsachata, an older andesitic cinder cone surrounded by a lava shield, which erupted ca. 11,500 years ago, and a younger rhyolitic lava dome, Oroscocha, that erupted ca. 6400 years ago and produced a short, thick lava flow. (USGS / GVP)
