Anak Krakatau blasts ash nearly 10 miles high
The Anak Krakatau volcano in Indonesia experienced a major eruption in September 2026, sending ash plumes up to 50,000 feet into the atmosphere. The event caused significant disruption to air travel and degraded air quality across Java and Sumatra.
Why it matters
Volcanic activity in this region poses ongoing risks to aviation safety and public health for millions of residents in Indonesia.
A powerful eruption at Indonesia's Anak Krakatau sent ash high into the atmosphere, disrupting thousands of flights and worsening air quality across parts of the country.
Anak Krakatau is a small but highly active volcano located between the Indonesian islands of Java and Sumatra. Its eruptions are often relatively modest, but the volcano is also capable of producing much more hazardous activity. In early September 2026, Anak Krakatau entered a prolonged explosive phase that lasted for more than 24 hours, sending large amounts of gas and ash into the sky. The eruption disrupted air travel and contributed to poor air quality in several areas, including Jakarta.
