Do, 3. Feb 2022, 00:27 00:27 AM | VON: VN
AVO reported that low-level eruptive activity at Semisopochnoi's North Cerberus cone continued during 25 January-1 February. Seismicity was elevated, characterized by periods of tremor and small earthquakes. Steam and low-level ash emissions likely occurred daily, though due to weather clouds they were only confirmed in webcam images during 25-26 and 29-31 January and 1 February.
Numerous small explosions were recorded by local seismic and infrasound sensors during 29 January-1 February. The Aviation Color Code remained at Orange and the Volcano Alert Level remained at Watch.
