Fourpeaked Volcano Activity in Alaska

Current Level of Concern Color Code: YELLOW.  Volcanic unrest continues at Fourpeaked volcano. Scientists from the University of Maryland-Baltimore County indicate that sulfur dioxide emission is continuing. Early in the week, vents from the volcano were emitting steam and other volcanic gasses. Thermal measurements of up to 167 degrees (Fahrenheit) were recorded at the vents, although steam was likely obscuring hotter areas. Airborne gas measurements documented high emission rates of sulfur dioxide, hydrogen sulfide, and carbon dioxide, and a distinct sulfur smell was evident up to 30 miles from Fourpeaked's summit. Deep scouring of a glacier flowing west from the summit indicated flooding, probably from the September 17th event. Observations strongly suggest the presence of new magma at shallow levels beneath the volcano. It remains possible that a significant eruption could occur in the coming days or weeks. (Alaska Volcano Observatory)
