Indonesia's Mount Anak Krakatau has been erupting since early September 2026, producing lava fountains and volcanic ash. Authorities have confirmed the activity is ongoing but stated there is no current risk of a tsunami.
Why it matters
Monitoring volcanic activity in the Pacific Ring of Fire is critical for public safety and disaster preparedness in seismically active regions.
Indonesia's Mount Anak Krakatau erupted overnight into Saturday, spewing rocks and volcanic ash into the air, the country’s Geological Agency said, AzerNEWS reports, citing Tribune.
“As of today, September 5, 2026, at 4:40am Western Indonesian Time, the eruption is still ongoing, and rumbling can still be heard from the Krakatau Pasauran PGA Post,” the agency said in a statement.
The volcano's eruptions have continued since July 2, when its alert status was raised to Level III, local media outlet Tempo reported.
“The height of the eruption column was not observed, but the bright red colour of the eruption plume was clearly visible,” the report said.
MAGMA Indonesia, a digital platform that provides real-time information about geological hazards across the country, said seismic activity linked to the eruption was recorded from Friday morning, with the seismograph registering a maximum amplitude of 33 millimetres and a duration of 14 seconds.
