Mount Erebus, situated in Antarctica, holds the distinction of being the world’s southernmost active volcano. Notably, it is the only volcano of its kind, currently erupting as a phonolite volcano. Recent reports highlight an astonishing phenomenon associated with this volcano – it is spewing gold dust, making headlines globally.
Gold Eruption
According to the National Aeronautics and Space Administration (NASA) Earth Observatory, Mount Erebus is emitting approximately $6000 worth of gold dust each day. This daily output, equivalent to more than Rs 5 lakhs in Indian currency, has garnered significant attention. The ejected gold dust, estimated at around 80 grams daily, is dispersed in the form of crystallized gold particles.
Mechanism and Reach
Reports from IFL Science and Hindustan Times elucidate the process behind the gold emission. The volcano expels gold dust within pockets of gas, propelling it to distances as far as 621 miles away from the eruption site. Mount Erebus, towering at 12,448 feet, not only claims the title of the tallest active volcano in Antarctica but also boasts a reputation for its extreme volatility.
Accessibility and Monitoring
Despite the allure of the gold phenomenon, accessibility to Mount Erebus remains a formidable challenge due to its remote location. Consequently, the gold dust remains beyond reach for individuals seeking to capitalize on the eruption. However, scientists and researchers utilize satellite technology for continuous monitoring of the volcano’s activity.
