No evidence of eruptive activity at Pavlof over the past day. Seismic activity remains very low. Satellite observations in the past 24 hours show no evidence of elevated surface temperatures. No ash or gas emissions have been detected in satellite data, web camera images, or reported by pilots.

During earlier periods of the current eruption and past eruptions of Pavlof, the style of eruptive activity has fluctuated from higher to lower levels. Such a fluctuation occurred during the current eruption on May 28, when eruptive activity paused until resuming on June 4. Therefore, the current pause in eruptive activity does not necessarily indicate that the eruption has ended. Renewed activity is possible, and may not be preceded by significant seismic activity. AVO will continue to monitor Pavlof closely.
