Shishaldin volcano (Aleutian Islands, Alaska) activity update: elevated seismicity; weak gas plume

Thursday Mar 26, 2020 07:57 AM | VON: MARTIN

The Alaska Volcano Observatory (AVO) reported that seismicity remains elevated with continuous low-level tremor. Satellite and web camera views were mostly obscured by clouds over the past 24 hours, but one relatively clear image showed a small gas plume emanating from the summit of the volcano. Eruptive activity appears confined to the summit area during this most recent period of unrest, which started mid-March. Activity could increase with little or no warning, however, resulting in lava flows and lahars outside of the crater and (or) ash emissions.

Friday, Mar 20, 2020
The Alaskan Volcano Observatory (AVO) report that the eruptive activity continues at Shishaldin volcano. Minor explosive activity has subsided over the past 24 hours, but seismicity remains elevated with near-continuous tremor. A small steam plume from the summit was observed over the past 24 hours. For now, eruptive activity looks as if it is confined to the summit area, but activity could increase with little or no warning resulting in lava flows outside of the crater, lahars, and ash emissions.

Monday, Feb 10, 2020
The Alaskan Volcano Observatory (AVO) report that no significant eruptive activity has occurred over the past 24 hours. No significant seismic data has been detected also. Weakly elevated surface temperatures and a small steam plume were observed in satellite images. Rare clear webcam views also showed this steam plume. AVO note that it remains possible for unrest to escalate at any time with little warning, and additional lava flows, lahars, and ash-producing eruptive events may occur. [mehr]
