A 50-50 chance of an eruption is looming over Mount Spurr volcano in Alaska, sparking concerns from scientists. Ten months of unrest at the mountain has increased seismic activity, with earthquakes migrating to a new area near a side vent called Crater Peak. This vent last erupted in 1992 and produced massive ash columns.
The Alaska Volcano Observatory (AVO) warns that Mount Spurr’s magma movement could lead to an eruption from the side vent or main crater. The volcano’s frequent earthquakes have increased, with the location shifting towards Crater Peak. There’s no clear indication of a summit eruption, but a flank eruption would send avalanches of hot ash and mud cascading down the mountain.
If an eruption occurs, it could disrupt flights at Anchorage airport and affect air travel between North America and Asia. Ashfall could also impact nearby communities. Experts are closely monitoring seismic activity, looking for signs of a longer-duration tremor that would indicate more certain eruption.
