Mount Spurr Remains at Elevated Unrest Amid Earthquake Surge Near Anchorage

Seismic activity at Alaska's Mount Spurr has surged back to levels last seen in March, raising concerns about a potential volcanic eruption near Anchorage, a city of nearly 300,000 residents. The Alaska Volcano Observatory (AVO) reported around 100 earthquake events per week, caused by magma rising and putting pressure on surrounding rock, which could lead to an eruption, though the likelihood is said to be gradually declining. Despite the elevated state of unrest, experts note no current signs that the volcano is imminently moving toward an eruption, emphasizing that any eruption would be preceded by additional warning signals. The volcano's summit crater has not erupted in approximately 5,000 years, but its side vent, Crater Peak, last erupted 30 years ago and is the more likely source if an eruption occurs. Residents have begun preparing by stocking up on supplies and protective gear due to the uncertainty, while officials continue to monitor the situation closely. Scientists describe the current period as a frustrating phase, uncertain whether the activity is ramping up or down, but caution that the risk remains significant.
