An increase in seismic activity at Pavlof Volcano, which erupted spectacularly in March, has prompted Alaska Volcano Observatory staff to step up monitoring of the Alaska Peninsula volcano. In a brief update Friday, raising Pavlof’s alert level to watch and its aviation color code to orange, staff at the observatory said they haven’t been able to visually confirm any eruption from satellite data or camera images, due to clouds obscuring the volcano.

“At about 10:35 a.m. (Alaska time) seismic activity at Pavlof Volcano increased to levels typically associated with low-level eruptive activity and it is possible that an eruption of Pavlof Volcano may be in progress,” AVO staff wrote. AVO spokesman Dave Schneider said that the seismic activity that led to Friday’s notice for Pavlof has been increasing in intensity, although there’s still no confirmation that “anything is coming out of the volcano.” READ MORE
