Mount Spurr, which sits about 75 miles west of Anchorage, has seen “ volcanic unrest ” for the last 10 months, including an increasing number of earthquakes, according to a Feb. 6 statement from the Alaska Volcano Observatory. The unrest suggests “that an eruption is possible,” officials said.

An active volcano near Alaska's most populated city could be on the brink of eruption, according to scientists who are constantly monitoring a potential threat.
