![]() ![]() This report covers intermittent pyroclastic flows, incandescent avalanches, and ash eruptions during January through June 2022 using daily and VONA reports from the Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG, also known as Indonesian Center for Volcanology and Geological Hazard Mitigation, CVGHM), the Darwin Volcanic Ash Advisory Centre (VAAC), and various satellite data.Īctivity during January 2022 consisted of continuous nighttime crater incandescence, gray-white ash emissions, and occasional pyroclastic flows and avalanches. As a result, several communities were partially buried, causing fatalities and significant damage. An eruption and dome collapse occurred near the summit on 4 December 2021, which produced a notable ash plume and pyroclastic flows, the latter of which generated major lahars (BGVN 47:01). The current eruption has been ongoing since April 2014 and has more recently consisted of explosions, ash plumes, lava flows, pyroclastic flows, lahars, and dome collapse. Eruptions have been characterized by Vulcanian and Strombolian explosions, lava flows, pyroclastic flows, lava domes, and lahars. Hundreds of eruptive events occurred during the 19th and 20th centuries, including nearly continuous activity since 1967. Semeru, located in East Java, Indonesia, contains the active Jonggring-Seloko vent at the Mahameru summit.
