A lava flow at Quimsachata scoria cone is visible in this October 2020 Planet Labs satellite image monthly mosaic (N is at the top). The flow erupted about 11,500 years ago and is approximately 4.7 km in the NW-SE direction. The smaller lava flow directly to the north was erupted from the Oroscocha lava dome about 6,400 years ago. These are the northernmost young volcanic centers in Perú.

Sintesi geologica

The Quimsachata-Oroscocha group consists of two late Pleistocene and Holocene monogenetic volcanoes at the foot of the Cordillera Oriental, far east of the main volcanic front. Quimsachata is a high-potassium andesitic scoria cone surrounded by a lava shield that was erupted in flat terrain along the Vilcanota River about 11,500 years ago. Oroscocha is a rhyolitic lava dome with a short, thick lava flow erupted from a N-S-trending fissure about 6,400 years ago.

This volcano is constructed from two separate centres, one active 11,500 years ago which formed a scoria cone and a lava field and another active 4450 BCE which formed two lava flows and a lava dome.
