AVO reported that low-level eruptive activity at Semisopochnoi's North Cerberus cone continued during 21-27 June. Periods of low-amplitude tremor and a few small low-frequency earthquakes were recorded by the seismic network. Weather clouds often prevented satellite and webcam views; sulfur dioxide emissions were detected in satellite images during 23-24 June and a robust steam plume was visible in webcam images during 25-26 June.
The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.
