Tupungatito

Stratovolcano · Chile-Argentina · 5660m

Tupungatito volcano, the northernmost historically active volcano of the central Chilean Andes, is the broad, glacier-clad massif at the right center. The glacial icecap fills the southern side of the Pleistocene Nevado Sin Nombre caldera, which is breached to the NW, in the direction of this photo. A dozen Holocene craters are found at Tupungatito, which has produced frequent mild explosive eruptions during the 19th and 20th centuries. Tupungatito is located immediately SW of Pleistocene Tupungato volcano, the large conical peak at the left.

Geological summary

Tupungatito volcano, the northernmost historically active volcano of the central Chilean Andes, is located along the Chile-Argentina border about 90 km E of Santiago and immediately SW of the Pleistocene Tupungato volcano. Tupungatito consists of a group of 12 Holocene andesitic and basaltic andesite craters and a pyroclastic cone at the NW end of the 4-km-wide, Pleistocene dacitic Nevado Sin Nombre caldera, which is filled by glaciers at its southern end and is breached to the NW. Lava flows from the northernmost vent have traveled down the NW flank breach. Tupungatito has produced frequent mild explosive eruptions during the 19th and 20th centuries.

From Wikipedia

Volcán Tupungatito is the northernmost historically active stratovolcano of the southern Andes. Part of the Chilean Andes' volcanic segment, it is the northernmost member of the Southern Volcanic Zone (SVZ), which is one of several distinct volcanic belts in the Andes. Over 70 Pleistocene or Holocene age volcanoes make up this volcanic belt, which on average has one eruption per year.
