Increased seismic activity at Mount Spurr raises eruption concerns in Alaska

Mount Spurr, a volcano in Alaska, is experiencing increased seismic activity, particularly near Crater Peak. This follows ten months of small earthquakes, with a recent uptick in tremors suggesting possible magma movement beneath the volcano. The Alaska Volcano Observatory estimates a 50 percent chance of an eruption at Crater Peak, which last erupted in 1992. While the current activity resembles past events, previous seismic unrest did not lead to eruptions. If an eruption occurs, it could cause hazards like ashfall and disrupt air travel, similar to the 1992 eruption that affected Anchorage's airport. Scientists are closely monitoring the situation for any signs of an imminent eruption.
