Scientists at the US Geological Survey have detected a significant uptick in earthquakes around Alaska’s Mount Spurr volcano, leading to concerns about an impending eruption. The volcano, located 75 miles west of Anchorage, has been experiencing increased unrest over the past 10 months.
According to Matthew Haney, scientist in charge of the Alaska Volcano Observatory, there is a 50% chance of an eruption, triggered by small earthquakes, swelling of the surface, and melting of snow and ice at the summit. This increase in activity was seen during the last major eruption in 1992, which followed nine months of earthquake activity.
The volcano alert level has been raised to “watch” due to heightened unrest, with scientists closely monitoring for signs of volcanic tremor, a continuous shaking that can signal an impending eruption. If detected, this would likely lead to an increased alert level.
An eruption at Mount Spurr could have significant impacts on the surrounding area, including the city of Anchorage, which is about 75 miles away. The volcano’s proximity to the population center makes it a high-threat volcanic system.
However, scientists emphasize that there is still uncertainty and no indication of ongoing gas emissions. “We’re still diagnosing what is happening inside of Mount Spurr,” Haney said. While some eruptions may occur, others do not.
