AVO reported that low-level eruptive activity at Semisopochnoi's North Cerberus cone continued during 3-10 May. Seismicity continued to be elevated with intermittent tremor detected by the seismic network. Several daily explosions were recorded during 8-10 May.
Weather clouds obscured views of the volcano, though daily minor, low-level ash emissions were seen in webcam views. A pilot reported a low-level eruption cloud on 9 May. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.
