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 05 Jul 2023 10:04.
BPPTKG reported that the eruption at Merapi (on Java) continued during 23-29 June and seismicity remained at elevated levels. The SW lava dome produced 130 lava avalanches that traveled as far as 2 km down the SW flank (upstream in the Boyong drainage) and one that traveled 300 m NW down the Senowo drainage. Morphological changes to the SW lava dome were due to continuing collapses of material. The Alert Level remained at 3 (on a scale of 1-4), and the public was warned to stay 3-7 km away from the summit based on location.
