Eruption Imminent? Alaska’s Mount Spurr Emits Massive Steam Plume, Raising Volcano Alert Levels

A significant steam plume has been spotted rising from Mount Spurr in Alaska, indicating heightened volcanic activity. Visuals provided by the Alaska Volcano Observatory (AVO) on March 28 showed steam and gas being emitted from the summit of the volcano as well as a vent on its northern side. The volcano, which is approximately 80 miles west of Anchorage, reaches an elevation of 11,070 feet. Experts have indicated that a potential eruption may occur in the weeks or months ahead, although no definitive predictions can be made at this time.

Reported Increased Volcanic Activity

The most recent report from the Alaska Volcano Observatory noted steam ascending from the summit on March 26. A smaller plume was also detected from a fumarole on the volcano’s northern side. No immediate shifts in seismic activity or gas concentrations were observed during these evaluations, according to AVO’s report.

Previously, the AVO noted in a March 11 update that a significant increase in gas emissions suggests that new magma has been introduced into the crust beneath Mount Spurr. This information has led scientists to evaluate the potential for an imminent eruption. The observatory emphasized that the exact timing of any volcanic activity remains uncertain.

Potential Risks and Alerts

The observatory has issued warnings that the volcano’s alert level could be elevated should further signs of activity emerge. According to AVO, indicators could include ongoing seismic tremors, heightened gas outputs, or noticeable physical changes on the surface. In the event of an eruption, potential risks encompass ash clouds disrupting flights, ashfall in surrounding areas, pyroclastic flows, and lahars, which are destructive mudflows.

The last eruption of the volcano took place in 1992, resulting in significant ashfall that impacted local air travel. The AVO advises residents and visitors to remain vigilant and adhere to safety guidelines if alerts are issued.
