Mount Erebus: Antarctica’s Gold-Spewing Volcano

Mount Erebus, located in Antarctica, stands as the most southerly active volcano on Earth, reaching an elevation of nearly 12,500 feet above sea level. This geological marvel releases approximately 800 grams of gold into the air daily, translating to about $6,000 worth of crystallized gold.

The unique environment of Mount Erebus, situated above a thin layer of the Earth's crust, facilitates the rise of molten rock from the interior. This process results in the emission of gas bubbles containing gold particles, which are then dispersed into the atmosphere. Despite the substantial daily release, the gold particles are too small and scattered to attract gold prospectors.

The phenomenon of gold emissions from Mount Erebus has intrigued scientists since it was first documented in 1991 by NewScientist as a 'geological curiosity.' The cold Antarctic air passing over the lava lake creates conditions conducive to the formation of thousands of gold particles. These particles, measuring about 60 microns—roughly half the thickness of a human hair—can be found up to 1,000 kilometers from the crater.

Mount Erebus is not only a source of fascination for its gold emissions but also holds a place in history due to a tragic event. In 1979, an Air New Zealand plane crashed into the side of the volcano, resulting in the loss of all passengers on board. This incident brought international attention to the otherwise remote and inhospitable region.

As one of the 138 most active volcanoes on Earth, Mount Erebus continues to be a subject of scientific study and curiosity. Its unique ability to release gold into the atmosphere sets it apart from other volcanic sites, offering insights into the geological processes occurring beneath the Earth's surface.
