HeureMag. / DepthDistanceLocation
Monte Burney is a large active stratovolcano in the Patagonian region of Chile, located about 200 km NW of the town of Punta Arenas. It is the southernmost active stratovolcanoes of the volcanic chain of the Australandean arc.
The only known historical eruption of Monte Burney took place in 1910, but there are many tephra layers from eruptions within the past few thousands years that could be dated by the C14 radiocarbon method and form important marker layers in Patagonia.

Introduction:

The glaciated volcano sits on the western rim of a 6 km wide caldera, which is partially filled with and surrounded by a large unglaciated pyroclastic-flow deposit. The volcano has had many flank eruptions that produced andesitic-dacitic lava flows and tephras. A major debris avalanche resulted from a collapse of the edifice and has traveled to the SSW.
Eruptions of Mt Burney volcano:
Evidence of 2 large plinian eruptions from Monte Burney during the Holocene has been found in wide-spread tephra layers. An eruption 3,830±390 years ago is believed to have severely impacted forest and aquatic ecosystems southeast of the volcano. Release of SO2 produced soil and lake acidification, nutrient leaching, and increased soil erosion.
