Updates on volcanic activity (Smithsonian)

The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Merapi report has been published on 04 Aug 2021 09:22.
BPPTKG reported that the lava dome just below Merapi?s SW rim and the lava dome in the summit crater both remained active during 23-29 July. The SW rim lava-dome volume was an estimated 1.878 million cubic meters and material continued to collapse down the flank. The volume of the summit lava dome was 2.817 million cubic meters. A total of four pyroclastic flows descended the SW flank as far as 2.5 km. Lava avalanches traveled a maximum of 1.2 km SE (29 times), 2 km SW (145 times), 800 m W (four times), and 500 m NW (one time). Avalanches of material that descended the W flank originated from lava emplaced in 1992 and 1998, and material that descended the NW flank is from 1948 lava. The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 5 km away from the summit. Source: Balai Penyelidikan dan Pengembangan Teknologi Kebencanaan Geologi (BPPTKG)
