Monte Burney

Burney, Monte

Stratovolcano · Chile · 1758m

Ice-covered Mount Burney occupies the NW part of the Muñoz Gomera Peninsula in the spectacular glaciated Patagonian fjord region of southern Chile. The volcano lies near the center of this NASA International Space Station image (with north to the left). The rugged extensively glaciated topography surrounding the 1758-m-high Monte Burney is smoothed by volcaniclastic deposits from the volcano.

Geological summary

Monte Burney, a large ice-covered volcano in the Patagonian region of Chile, lies about 200 km NW of the town of Punta Arenas. It was constructed on the western rim of a 6-km-wide caldera, which is partially filled with and surrounded by an unglaciated pyroclastic-flow deposit. Flank vents produced andesitic-dacitic lava flows and pyroclastic material. Collapse of the edifice produced a major debris avalanche that traveled to the SSW. Two large Plinian eruptions have been documented during the Holocene. The only known historical eruption took place in 1910.
