Krakatau Really Erupted. The Viral 'Footage' Was AI, Recycled From Ten Months Earlier.

Reverse-image and keyword searches traced the footage to a TikTok post from November 5, 2025 — ten months before the real eruption it was being passed off as ^[1]. The video is synthetic, not repurposed real footage from elsewhere. The eruption is never visible on the phone screens of the people supposedly filming it, and the smoke changes color unnaturally, shifting from bright purple to red to orange in ways inconsistent with real volcanic plumes ^[1][2].

Meta's own AI-content analysis tool flagged the clip as generated with one of its models, and separate testing by fact-checkers using NVIDIA and Hive AI-detection tools reached the same conclusion ^[1][2]. Indonesia's National Disaster Mitigation Agency (BNPB) and its Geological Agency both publicly dismissed the clip as a hoax ^[1].

Anak Krakatau did erupt for real, late on September 5 into September 6, 2026, sending ash across Greater Jakarta and Lampung and grounding air travel across the region ^[3]. Eight airports closed, including Jakarta's Soekarno-Hatta International, the country's main gateway; four remained shut into the following Monday ^[3]. More than 270,000 passengers were stranded and 1,558 flights delayed or cancelled, over 900 of them at Soekarno-Hatta alone ^[3].

Indonesia's Transportation Minister, Dudy Purwagandhi, announced alternative airports in Semarang and Surabaya to absorb diverted traffic, while BNPB chief Suharyanto said heavy rain would help wash the ash away ^[3]. No deaths were reported and no villages were evacuated ^[3].

FALSE. Anak Krakatau's eruption and the travel chaos it caused were real, but the widely shared video was not footage of it — it was an AI-generated clip first posted ten months earlier, recirculated to look like breaking disaster coverage ^[1][2]. The fake video didn't need to be flawless; it only needed to arrive at the right moment, riding a real news event that made it instantly believable. Indonesian authorities have confirmed the footage does not depict the current eruption ^[1].
