Viedma, Volcanic peak in Southern Patagonia, Chile
The Viedma volcano reaches an elevation of 1300 meters and contains four separate calderas ranging from 1.5 to 4 kilometers in diameter.
The 1988 volcanic eruption produced substantial ash and pumice deposits on the Patagonian glacier, generating a mud flow that extended to Viedma Lake.
The volcano holds geological importance for understanding the early Mesozoic connection between Patagonia and the Antarctic Peninsula through rock formations.
Scientific research teams access the volcano site to study metamorphic rocks at Nunatak Viedma and analyze volcanic deposits beneath the ice field.
The volcano sits beneath the Southern Patagonian Ice Field, making it one of the few subglacial volcanoes in South America.
