Updates on volcanic activity (Smithsonian)

The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Semeru report has been published on 09 Mar 2022 07:30.
PVMBG reported that the eruption at Semeru continued during 2-8 March, causing the observatory to issue several VONAs mostly for ash plumes. Ground observers noted an ash plume at 0540 on 3 March that rose vertically 4.2 km above the summit. At 2004 later that day a pyroclastic flow originating from the end of a lava flow descended the Kobokan drainage on the SE flank; an ash plume was not visible. Ash plumes at 0742 on 5 March, and at 0603 and 0734 on 6 March, rose 400-500 m above the summit and drifted N and NW. Ash plumes at 0534 and 0735 on 7 March rose 1 km and drifted SSE and NW, respectively. More ash plumes at 0541 and 0758 on 8 March rose 400 m and drifted SW and S. The Alert Level remained at 3 (on a scale of 1-4). The public was warned to stay at least 500 m away from Kobokan drainages within 17 km of the summit, along with other drainages originating on Semeru, including the Bang, Kembar, and Sat, due to lahar, avalanche, and pyroclastic flow hazards.
