Ash emissions and lava spray and flow are typical for Veniaminof. Ash usually stays contained in the summit crater but can occasionally fall in nearby areas. The Alaska Volcano Observatory raised the aviation color code to orange to warn pilots in the area of possible ash emissions.
A small explosion was detected at the Veniaminof Volcano early Thursday morning at 5:13 a.m. The volcano is located on the Alaska Peninsula north of Perryville.
Satellite and webcam footage revealed small deposits of ash near the summit. The ash cloud stayed below 10,000 feet.
The Alaska Volcano Observatory raised the aviation color code to orange to warn pilots in the area of possible ash emissions. Color code orange means there is heightened unrest at a volcano with an increased potential for eruption, but that the risk is limited.
Geologists observed sulfur in the area over the past few days and a rise in surface temperature Wednesday night.
Ash emissions and lava spray and flow are typical for Veniaminof. Ash usually stays contained in the summit crater but can occasionally fall in nearby areas. A satellite link at Port Heiden is out, so local seismic activity is offline at this time. The volcano observatory continues to monitor the situation.
