AVO reported that a minor eruption at a vent on Pavlof?s upper E flank was ongoing during 3-9 August.
Seismic tremor persisted and multiple daily explosions were detected in local and regional seismic and infrasound data.
The explosions likely produced minor ash emissions that rose no higher than 3 km (10,000 ft) a.s.l., though cloud cover prevented confirmation on most days.
Strongly elevated surface temperatures were identified in satellite images during 7-8 August.
The Volcano Alert Level remained at Watch and the Aviation Color Code remained at Orange.
