Pavlof volcano news & activity updates:
Sun, 29 Dec 2019, 15:10
Pavlof volcano visible from space captured by satellite on 28 December (image: Sentinel 2) The Alaska Volcano Observatory (AVO) reported that seismic activity has increased at the volcano over the past days. The seismic activity represents an increase from background levels. Read more...No eruptive activity or emissions from the summit have been observed. The Aviation Color Code and Alert Level have changed to Yellow/Advisory. This does not mean that an eruption is likely or imminent. Past eruptions of Pavlof occurred with little or no warning. [ less] Thu, 7 Nov 2019, 08:26
The Alaska Volcano Observatory (AVO) lowered the alert level back to GREEN/NORMAL. Read more...Since small explosion signals had last been detected on 19 Oct, no other signs of activity or unrest have been found since then. [ less] Thu, 31 Oct 2019, 09:06
Pavlof volcano visible from satellite Sentinel on 29 October (image: Sentinel) AVO reported that after a small explosion at Pavlof was recorded on 19 October and before 25 October clear satellite and webcam views did not show any deposits associated with the event. Weakly elevated surface temperatures and a small steam plume were occasionally visible. Read more...No other activity was detected during 26-29 October. The Aviation Color Code remained at Yellow and the Volcano Alert Level remained at Advisory. Source: Smithsonian / USGS Weekly Volcanic Activity Report 23 October-29 October 2019 [ less] Thu, 24 Oct 2019, 14:51
Clouds obscured satellite views of the volcano (image: AVO) On 19 October small explosion signals at Pavlof were detected by the infrasound network located at Sand Point and on the local seismic network, prompting AVO to raise the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory. Read more...Clouds obscured satellite views of the volcano around the time of the event. Slightly elevated surface temperatures were detected in satellite images during 19-20 October. Source: Smithsonian / USGS Weekly Volcanic Activity Report 16 October-22 October 2019 [ less]
Sun, 20 Oct 2019, 06:58
The Alaska Volcano Observatory (AVO) recorded small explosion signals from the volcano via its infrasound network located at Sand Point and on the local seismic network yesterday. Read more..."It is unknown if the explosions produced any volcanic ash, but their small size suggests any hazard is currently confined to the area around the volcano's summit. Because these signals are above normal background for Pavlof, the Alaska Volcano Observatory is raising the Aviation Color Code to YELLOW and the Alert Level to ADVISORY." (AVO) [ less] Thu, 13 Jun 2019, 05:51
The elevated seismic activity observed in mid May has again declined to background levels. TRhe Alaska Volcano Observatory lowered the Aviation Color Code and Alert Level to GREEN/NORMAL.
Wed, 15 May 2019, 23:26
Low-level seismic tremor and increased steaming has been observed; Pavlof is notorious for not giving much warning before erupting so AVO has raised the alert as a new eruption may start at any time.
