Mount Spurr in Alaska is exhibiting alarming signs of potential eruption, with researchers indicating a 50% probability based on increased seismic activity from 30 to 125 earthquakes per week. Seismologists from the Alaska Volcano Observatory suggest the activity stems from magma movements beneath the volcano. While there are no communities likely to be impacted by devastating flows, the ash produced during an eruption could pose serious health risks, reminiscent of the 1992 eruption that disrupted Anchorage and its airports with ash fallout.
If Mount Spurr erupts, it could produce explosive plumes of ash and dangerous mudslides, with no communities in the immediate path of pyroclastic flows.
Scientists at the Alaska Volcano Observatory believe the recent sustained increase in seismic activity is a sign of new magma rising beneath the volcano.
