Monte Burney
Monte Burney is a volcano in southern Chile, part of its Austral Volcanic Zone which consists of six volcanoes with activity during the Quaternary. This volcanism is linked to the subduction of the Antarctic Plate beneath the South America Plate and the Scotia Plate. Monte Burney is formed by a caldera with a glaciated stratovolcano on its rim. This stratovolcano in turn has a smaller caldera. An eruption is reported for 1910, with less certain eruptions in 1970 and 1920. Tephra analysis has yielded evidence for many eruptions during the Pleistocene and Holocene, including two large explosive eruptions during the early and mid-Holocene. These eruptions deposited significant tephra layers over Patagonia and Tierra del Fuego. Name The volcano is named after James Burney, a companion of James Cook. It is one of the many English language placenames in the region, which are the product of the numerous English research expeditions such as these by Robert FitzRoy and Phillip Parker King in 1825–1830. Geography and geomorphology Monte Burney is on the northwest Muñoz Gomera Peninsula. This area lies in the Patagonian region of Chile, which is known for its spectacular fjords. The volcano lies in the commune of Natales northwest of
