Viral Video Claiming Anak Krakatau Eruption Deemed AI-Generated Hoax

A video circulating widely on social media platforms, including Instagram, Facebook, and TikTok, claims to capture a dramatic eruption of Mount Anak Krakatau. The footage depicts what appears to be a volcanic eruption with glowing red light and plumes of smoke ejected into the air, filmed from a ferry at night.

However, Tempo's Fact Check Team has investigated the claim and concluded that the video is a hoax. Using direct analysis, artificial intelligence detection tools, and cross-referencing with credible sources, the team found indications of AI-generated elements within the video. While Indonesia's Geological Agency confirmed minor eruptions from Mount Anak Krakatau in early July 2026, raising its alert status to Level III (Standby), the dramatic visuals in the viral video do not align with the actual conditions.

The Geological Agency stated in a written release on July 4, 2026, that "Following verification, the video is not footage of the current eruption of Mount Anak Krakatau. Therefore, the information is a hoax (false)." According to the agency's monitoring records, the volcano experienced only two minor eruptions on July 2 and July 3, 2026. These events were not characterized by the spectacular display seen in the viral video.

Further analysis revealed physical irregularities in the footage, such as the eruption alternating between purple and reddish colors, which is uncommon for actual volcanic events. An AI detection application also indicated a 59 percent probability that the video contained artificially generated content. Tempo's verification concluded that the claim is misleading, emphasizing that while the volcano was active, the widely shared video does not represent the reality of its recent eruptions and shows signs of manipulation.
