The city is among the communities surrounded by the Tongass National Forest. All rights reserved. Webcams on Thursday clearly showed episodic low-level ash emissions from Pavlof Volcano, prompting the observatory to raise the volcanos threat level from yellow, or exhibiting signs of unrest, to orange, indicating an eruption is underway with minor volcanic ash emissions. We expect additional shallow seismicity and other signs of unrest, such as gas emissions, elevated surface temperatures, and surface deformation to precede any future eruption, if one were to occur. California, Oregon, Washington, Alaska and . Willoya, who had set an early alarm to check for northern lights activity, had no idea what she was hearing. Weakly elevated surface temperatures and minor steaming from the active vent were observed in satellite data and web camera views several times during the week and may be related to the cooling of lava around the vent. The volcano is about 4.4 mi (7 km) in diameter and currently has an active vent on the east side close to the summit. Internally, how we think about Edgecumbe has changed.
