Raung (Indonesia) – Report for 26 August-1 September 2020 – NEW

The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian’s Global Volcanism Program and the US Geological Survey’s Volcano Hazards Program. Updated by 2300 UTC every Wednesday, these notices are preliminary and subject to change as events are studied in more detail. This is not a comprehensive list of eruptions during the week, but rather a summary of activity that meet selected criteria. Carefully reviewed, detailed reports are published monthly in the Bulletin of the Global Volcanism Network. The World Organization of Volcano Observatories (WOVO) website (http://www.wovo.org/) lists the regional volcano observatories that have the most authoritative data for many of these events.

A new eruption, or volcanic unrest was detected by volcanologists and published by the GVP. The details are summarized in the following message:

PVMBG reported that on 21 August white-and-brown emissions rose 100 m above Raung?s summit and drifted N and S. White plumes rose as high as 100 m during 22-26 August; weather conditions prevented visual observations during 27-31 August. The Alert Level remained at 2 (on a scale of 1-4), and the public was warned to remain outside of the 2-km exclusion zone.
