  "account": "Residents in West Java, Banten, and Lampung reported rumbling and vibrations on Friday night to Saturday morning, September 4-5, 2026. Experts believe these seismic activities were caused by the eruption of Mount Anak Krakatau in the Sunda Strait. Rita Susilawati, head of the Centre for Volcanology and Geological Hazard Mitigation (PVMBG), confirmed this during a virtual press conference on September 5, 2026. Similar rumblings were heard in 2020 during eruptions of other Indonesian volcanoes, further supporting the connection. The Meteorology, Climatology, and Geophysical Agency (BMKG) reported no significant tectonic earthquakes in the region during the time of the rumbling. Rita noted that the coincidental timing of the rumblings and the eruption provided a correlation, although it did not confirm the source definitively. She also cited the example of the 2014 Kelud eruption, which caused rumblings to be heard in distant areas like Yogyakarta and Central Java. Mount Anak Krakatau's lava fountain eruption usually generates loud rumbling sounds, releasing acoustic energy that can travel hundreds of kilometers. The eruption was ongoing until Saturday morning, September 6, 2026, and remained at Alert Level III, with a 3-kilometer danger zone around the volcanic activity center.",
