Brown Bluff

From Wikipedia, the free encyclopedia

Brown Bluff is a tuya located at the northern tip of the Antarctic Peninsula, Antarctica. It formed in the past 1 million years, which erupted subglacially within an englacial lake. The volcano's original diameter is thought to have been about 12-15 kilometers, and probably formed by a single vent. Brown Bluff is subdivided into four stages: pillow volcano, tuff cone, slope failure, and hyaloclastite delta and into five structural units.[1]

The volcano is named "Brown Bluff" because of its steep slopes and its brown-to-black hyaloclastite.
