No visual or satellite observations of an ash cloud have been reported. AVO will continue to monitor the volcano closely and issue further Updates as the situation warrants. Eruptive activity could cause mudflows and some flooding in the Cathedral River valley north of the volcano. Airborne ash hazards to aircraft may be considerable if a large explosive event occurs but are much less severe during a typical Strombolian phase. Seismicity rates continue to register just below the highest rates yet observed.
Visual observations indicate ongoing lava fountaining from two vents near the summit of the volcano.
Regional cloud conditions, with tops to 24,000 feet, currently prevent observation of plume characteristics. Based on the level of seismicity and the nature of this current eruption, lava fountaining, lava flows, and localized, diffuse ash clouds are likely to continue for weeks or months. AVO will continue to monitor the volcano closely. Pavlof is located 600 miles southwest of Anchorage. These towns could expect light ash fall depending on wind direction and level of eruptive activity.
