Today’s Top Three News: Anak Krakatau Erupts as Six Indonesian Volcanoes Erupt on Aug. 31

Mount Anak Krakatau continued erupting overnight into Saturday, Sept. 5, with incandescent rocks and volcanic ash rising from the volcano in the Sunda Strait. The eruption has continued since July 2, when authorities raised its activity status to Alert Level III.

The Geological Agency said the eruption remained continuous and was accompanied by rumbling sounds. At 4:40 a.m. Western Indonesian Time on Sept. 5, the eruption was still ongoing, and observers could hear the sounds from the Krakatau Pasauran monitoring post. The height of the eruption column could not be observed, but the plume glowed bright red.

Another focus was the activity recorded on Aug. 31, when Mount Sinabung in Karo, North Sumatra, erupted after four years of inactivity. Authorities raised its status from Alert Level II, or Waspada, to Alert Level III, or Siaga.

As of today, September 5, 2026, at 4:40 a.m. Western Indonesian Time, the eruption is still ongoing, and rumbling can still be heard from the Krakatau Pasauran PGA Post.

Sinabung was one of six volcanoes reported to have erupted almost simultaneously that day. The other five were Mount Ibu in North Maluku, Mount Lewotobi Perempuan and Ili Lewotolok in East Nusa Tenggara, Mount Semeru in East Java, and Anak Krakatau in the Sunda Strait. The Center for Volcanology and Geological Hazard Mitigation, under the Geological Agency, addressed questions about whether the eruptions were linked.

As Sinabung’s activity intensified after a major eruption earlier in the week, Indonesian authorities evacuated 615 residents from Kuta Tengah village in Karo Regency. Berton SP Panjaitan, acting head of the National Disaster Management Agency’s Data, Information and Disaster Communication Center, said the evacuation was a precaution against volcanic hazards. The residents, from 211 families, were taken to an emergency response post in Sukatepu village, Naman Teran District.
