Updates on volcanic activity (Smithsonian)

The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Lewotobi report has been published on 12 Jun 2024 08:23.
PVMBG reported that eruptive activity at Lewotobi?s Laki-laki volcano increased during 26 May-9 June. Eruptive activity increased daily, and ash-and-steam plumes became taller, rising 100-900 m above the summit on average and drifting in multiple directions; dense ash emissions rose 1-1.1 km above them summit on 5 and 9 June. The number of volcanic earthquakes as well as earthquake signals indicating eruptive events and avalanches significantly increased. PVMBG noted that there was also a significant increase in other types of seismic signals, though those increases were unrelated to the eruption; repairs and changes to the seismic network resulted in better detection of seismic signals. Incandescence at the summit was visible in a 5 June webcam image, and Strombolian activity was periodically visible on 9 June. At 0900 on 10 June the Alert Level was raised to 3 (the second lowest level on a scale of 1-4) and the public was warned to stay outside of the exclusion zone, defined as a 3-km radius around Laki-laki crater, 4 km to the NNE, and 5 km on the NE flanks. Strombolian activity continued on 10 June and several ash emissions rose 600-1,000 m above the summit. Gray ash emissions rose 300-600 m above the summit and drifted SW and W on 11 June. The lava flows on the NE flank advanced 20 m during 29 February-9 April to a total length of 4.34 km; the advancement was due to gravitational forces and not eruptive activity, and no additional advancement had been recorded since.
