Mount Spurr's Increased Seismic Activity Raises Eruption Concerns

Alaska Volcano Observatory reports a 50% chance of eruption at Crater Peak, with potential impacts on air travel and ashfall.

Mount Spurr, located 75 miles west of Anchorage, Alaska, has experienced rising seismic activity over the past 10 months, with earthquake numbers increasing from 30 to 125 per week.
Earthquakes have shifted from the summit to the Crater Peak vent, which last erupted explosively in 1992 and 1953, ejecting ash plumes up to 65,000 feet high.
Scientists from the Alaska Volcano Observatory suggest magma movement beneath the volcano could lead to an eruption, though the likelihood of no eruption remains equal to that of an eruption at Crater Peak.
Potential hazards include ash clouds, ashfall, pyroclastic flows, and lahars, with ash likely posing the greatest risk to air traffic in the region, as seen during the 1992 eruption.
The volcano's alert level is currently at 'advisory,' and experts are closely monitoring for signs such as increased gas emissions, surface heating, and seismic activity that could signal an imminent eruption.
