According the Alaska Volcano Observatory, another volcano is rumbling to life on the Alaska Peninsula. Mount Veniaminof, an 8,225-foot peak 25 miles southwest of Chignik Lake and 485 miles from Anchorage, has rumbled to life since about June 8, when researchers saw a spike in seismic activity at the peak. On Thursday morning, satellite imagery revealed heightened surface temperature indicating a likely “eruption at the intracaldera cone” of the volcano, the AVO reported.

Veniaminof is a wide-diameter peak that features a huge caldera with an active portion located on the western side. AVO researchers report that there has been steam observed coming from the peak, but no ashfall has been sighted yet. Despite that, the observatory elevated the volcano’s alert level to “watch,” indicating that explosive activity could occur any time. They’re warning aviators to exercise caution when flying near the peak.

“Seismic tremors continue, indicative of low-level effusive activity and small explosions,” the AVO wrote. “No ash plumes have been observed this (Thursday) morning although clouds have obscured web camera views of the summit.”
