Overview
- Anak Krakatau produced repeated eruptions that sent high ash plumes into western Indonesian airspace, with a notable blast early on Sunday that was tracked by satellites and local monitoring agencies.
- Airport operations were progressively suspended and by Monday eight airports had been closed or restricted, disrupting roughly 1,500 flight movements and affecting about 170,000 passengers, according to transport ministry and airport operators.
- Authorities report no casualties and have not issued evacuations, but they maintain a 3-kilometre exclusion zone and say the latest eruptions do not pose an imminent tsunami risk based on current seismic readings.
- Health and safety guidance from disaster and health agencies urges people to wear masks and eye protection, limit outdoor activity, cover water supplies, and follow airline instructions as schools in some areas shifted to remote learning.
- Anak Krakatau formed after the 1883 Krakatoa explosion and caused a deadly 2018 tsunami when part of its flank collapsed, so officials warn ash drift, further eruptions or structural collapse remain possible and will continue to be monitored closely.
