Semeru volcano (Eastern Java) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 March-14 March 2023 (Continuing Activity)

PVMBG reported that the eruption at Semeru continued during 8-14 March. Weather clouds sometimes prevented views of the volcano, though ash plumes were visible each day. On 8 March white-and-gray ash plumes that were sometimes dense rose as high as 300-700 m above the summit and drifted N and NE.
During 9-10 March dense white, gray, and brown ash plumes rose 500-600 m and drifted SW and S. At least six white-and-gray ash plumes of variable densities were visible on 11 March rising 600-800 m and drifting N, W, and S. White-and-gray ash plumes rose 500-700 m and drifted N, NE, and SW during 12-14 March.
The Alert Level remained at 3 (on a scale of 1-4). The public was warned to stay at least 5 km away from the summit in all directions, 13 km from the summit to the SE, 100 m away from the banks of the Kobokan drainage as far as 17 km from the summit, and to avoid other drainages originating on Semeru, including the Bang, Kembar, and Sat, due to lahar, avalanche, and pyroclastic flow hazards.
