Mount Anak Krakatau\u2019s roughly 25- hour continuous eruption ended in the early hours of September 6, 2026, but the volcano remains highly active at Alert Level III with a high chance of further eruptions.<\/strong><\/p>\n\n\n\n

The continuous phase began late on September 4 (around 11:07 p.m. local time) and ended around 12:04 a.m. on September 6. Activity has since returned to its more typical intermittent Strombolian pattern, with black ash columns reaching up to about 300 meters above the summit. <\/p>\n\n\n\n

Monitoring from September 6- 7 recorded dozens of earthquakes (including 93 low- frequency and 98 hybrid\/multiphase events), plus other eruption- and emission-related seismic signals.<\/p>\n\n\n\n

PVMBG (the Volcanology and Geological Hazard Mitigation Center) <\/strong>has kept the 3 km exclusion zone in place around the activity center. <\/p>\n\n\n\n

Potential hazards if continuous activity resumes include incandescent rock fragments, heavy ashfall, hot clouds (pyroclastic flows), and lava flows. <\/p>\n\n\n\n

Residents, tourists, and shipping are barred from the zone. <\/p>\n\n\n\n

There is currently no tsunami threat<\/strong> from the ongoing activity (unlike the 2018 Sunda Strait tsunami<\/strong>, which was triggered by flank collapse rather than the eruption itself). Officials have urged coastal residents in Banten and Lampung to stay calm and rely on official updates.<\/p>\n\n\n\n

Volcanologists note that frequent eruptions are normal for this young, still- building volcano as material accumulates and the edifice grows. <\/p>\n\n\n\n

As long as the system remains open, major energy buildup is not necessarily indicated. The agency continues round- the- clock visual and instrumental monitoring<\/strong> and will reassess the alert level if conditions change significantly.<\/p>\n\n\n\n

The dramatic night photo (glowing red lava\/plume against a dark sky, with bright jagged streaks that appear to be volcanic lightning) matches the kind of imagery reported from the event, including views from Pasauran, Serang Regency, Banten, around September 5. Volcanic lightning is common in ash -rich eruptions due to charge separation in the plume.<\/p>\n\n\n\n
