Updates on volcanic activity (Smithsonian)

The Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG) reported that eruptive activity at Marapi (on Sumatra) continued during 24-30 September. Eruptive events at 1959 on 24 September and at 2116 on 26 September were recorded but weather conditions prevented visual confirmation. An eruptive event at 1831 on 26 September produced a dense white-and-gray ash plume that rose 1 km above the summit and drifted E.
