Andagua volcanic field

Andahua-Orcopampa

Medan gunung api · Peru · 4713 m

The cinder cones at the center and upper right, surrounded by a prominent field of lava flows, are located in the Andahua valley, known locally as the "Valley of the Volcanoes." The large 60 x 60 km scoria cone and lava field contains extremely youthful lava flows, some of which may be only a few hundred years old. The volcanic field was reported to have been active during the time of the Incas. Lava flows have repeatedly dammed the Río Andagua valley, and an existing small lake was impounded by the youngest lavas.

Ringkasan geologi

The Andahua-Orcopampa volcanic field in the Andahua (or Andagua) valley area, 20 km ENE of Nevados de Coropuna, is a large 60 x 60 km scoria cone and lava field. Known locally as the "Valley of the Volcanoes," the field lies in a series of deep NNW-SSE-trending, en-echelon valleys: Orcopampa, Andahua, and Ayo. The field contains youthful dominantly trachyandesitic cinder cones and lava flows that have destroyed buildings and may be only a few hundred years old. The area was reported to have been active during the time of the Incas and to have "become active again" in 1913. Lava flows have repeatedly dammed the Río Andagua valley, and an existing small lake was impounded by the youngest lavas.

Ringkasan Wikipedia

Ringkasan Inggris

The Andagua volcanic field is a volcanic field in southern Peru which includes a number of cinder cones, lava domes and lava flows which have filled the Andagua Valley. The volcanic field is part of a larger volcanic province that clusters around the Colca River and is mostly of Pleistocene age, although the Andagua sector also features volcanic cones with historical activity, with the last eruption about 370 years ago. Eruptions were mostly effusive, generating lava flows, cones and small eruption columns. Future eruptions are possible, and there is ongoing fumarolic activity. Volcanic activity in the field has flooded the Andahua valley with lava flows, damming local watersheds in the Laguna de Chachas, Laguna Mamacocha and Laguna Pumajallo lakes and burying the course of the Andagua River. The Andahua valley segment of the larger volcanic province was declared a geopark in 2015.
