Merapi volcano (Central Java) - Smithsonian / USGS Weekly Volcanic Activity Report for 9 March-15 March 2022 (Continuing Activity)
BPPTKG reported that parts of Merapi's summit lava dome collapsed during 9-10 March, sending pyroclastic flows as far as 5 km SE down the Gendol drainage. At around 2318 on 9 March ash plumes rose at least 3 km above the summit and drifted SE. Ashfall was reported in several villages downwind, including in the Kemalang, Sawangan, Dukun, and Selo sub-districts, and 50 people from Bale Rante Village evacuated.

The total volume that collapsed was an estimated 646,000 cubic meters, making the volume of the remaining dome material about 2,582,000 cubic meters.
Overall, during 4-10 March, there was a total of 101 lava avalanches and one pyroclastic flow that descended the Bebeng drainage on the SW flank a maximum distance of 2 km. Extrusion at the SW lava dome continued; the volume of the dome was an estimated 1.58 million cubic meters, similar to the previous few weeks. Pyroclastic flows in the Gendol drainage totaled 18 during the week, and there were 17 lava avalanches that traveled as far as 1.5 km.
Seismicity remained at high levels with an increase in the intensity of signals. The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 3-5 km away from the summit based on location.
