20:07 PM | ПЇЅПЇЅПЇЅПЇЅПЇЅ: VNAs many as 118 lava avalanches originating from the SW dome traveled a maximum of 2.5 km down the Bebeng drainage on the SW flank. On 28 March two pyroclastic flows were recorded on a seismogram that descended 2.5 km SW, one of which occurred at 1509. On 1 April a pyroclastic flow at 1500 descended 1.5 km down the SW flank.
Based webcam, satellite, and wind data, the Darwin VAAC reported re-suspended ash that rose to 100 m (300 ft) a.s.l. As many as 37 avalanches were detected, but the distance and direction were not observed. 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.

A pyroclastic flow (hot avalanche of lava particles and ash) descended the southwestern flank of the volcano at 15:00 local time today, reaching approx. 1500 m distance from the summit. It resulted from a partial collapse of the growing active lava dome at the southwestern rim of the volcano's summit crater. ... Read all

BPPTKG reported no significant morphological changes at Merapi's summit lava dome during 18-24 March, but the height of the dome below the SW rim had increased by 4 m. Seismicity remained at high levels; the intensity of the signals had increased compared to the previous week. As many as 51 lava avalanches originating from the SW dome traveled a maximum of 2 km down the Bebeng drainage on the SW flank. ... Read all
