The Alaska Volcanic Observatory on Wednesday said Mount Sprue is at risk of erupting in the coming weeks or months, which could affect residents 78 miles away in Anchorage City.
“The increased gas emissions confirm that new magma has invaded the Earth's crust beneath the volcano, indicating that an eruption may occur within the next few weeks or months, but not certain,” the observation deck wrote. Information Statement.
Volcanic gas emissions increased on the mountains on Tuesday.
No steaming has been observed within the Crater Peak in Mount Sprue for over 17 years.
The last known eruptions at Crater Peak occurred in 1953 and 1992, while the last known eruptions from the Spar Summit occurred thousands of years ago.
Each of these eruptions lasted several hours, producing hundreds of miles and minor ash clouds of ash and a small ash cloud of about a quarter-inch inch, in an Alaskan community in southern Alaska, according to a release from the Alaska Volcanic Observatory.
“At the current level of anxiety, we plan to carry out routine overflights to measure gas emissions, assess surface changes and measure surface temperatures,” the station wrote.
“We are considering adding additional surveillance equipment in response to current concerns.”
