BPPTKG reported no significant morphological changes at Merapi's summit lava dome during 1-7 April. Based on photo analyses, the volume of the SW lava dome was 1.7 million cubic meters while the central lava dome was 2.6 million cubic meters. Seismicity remained at high levels.
As many as 144 lava avalanches originating from the SW dome traveled a maximum of 2 km down the Bebeng drainage on the SW flank. A single pyroclastic flow traveled 1.5 km down the SW flank. 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.
