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 11 Nov 2020 17:32.
PVMBG and BPPTKG raised the Alert Level for Merapi to 3 (on a scale of 1-4) on 5 November because of increasing evidence of a potential eruption. The report noted that the number of earthquakes began increasing after the 21 June explosive eruption; seismicity intensified in October and continued an upward trend. Electronic Distance Measurement (EDM) data indicated a distance shortening of 4 cm between points in the NW just after the 21 June event, and then continued showing deformation at a rate of 3 mm per day through September. The rate increased to 9 cm per day in late October and reached 11 cm per day on 4 November. The seismicity and deformation rates were higher than the rates leading up to the extrusion of lava domes on 26 April 2006, but remained lower than the 2010 eruption precursory conditions. No morphological changes were visible; the lava-dome volume was an estimated 200,000 cubic meters on 3 November based on analyses of drone images. BPPTKG alerted 12 villages in hazardous areas spread across Yogyakarta and Central Java Province, and recommended that mining in local drainages and tourism around Merapi should cease. BNPB reported that after the Alert Level was raised 607 vulnerable people (children for example) were evacuated from Krinjing, Paten, and Ngargomulyo villages in Dukun District, Magelang Regency, and emergency supplies were sent to multiple susceptible communities.
