6 volcanoes erupting in Indonesia | Anak Krakatau eruption | Are the six Indonesian volcanoes connected? | Indonesia volcano eruption risk
Six volcanoes erupted in Indonesia within 24 hours, raising questions about whether the eruptions are connected. This video examines the latest Anak Krakatau eruption, the 170,000 passengers stranded by volcanic ash, and the real Indonesia volcano eruption risk. Are the six Indonesian volcanoes connected, or is this coincidence? We also look at the 2018 Anak Krakatau tsunami and the latest Anak Krakatau eruption update, including the impact on airports and flights.

Anak Krakatau is erupting again — and the ash is reaching extraordinary heights.
Anak Krakatau is erupting again — and the ash is reaching extraordinary heights.
Indonesia’s volcano produced a powerful eruption sequence beginning September 4, with ash plumes reaching as high as 50,000 feet (15,000 meters) and spreading across parts of Java, Sumatra, and surrounding airspace.
The eruption has triggered major disruption to aviation. Multiple airports were temporarily closed because volcanic ash entered affected airspace, while thousands of flights were cancelled or delayed and hundreds of thousands of passengers were affected.
Jakarta’s Soekarno-Hatta International Airport was among the facilities impacted.
But the eruption is not simply a single explosion. After a roughly 25-hour period of intense activity, Anak Krakatau remained active with intermittent eruptions, dark ash emissions, and localized earthquakes. Indonesian authorities have warned that further eruptions remain possible. And because Anak Krakatau is the volcanic island that emerged from the remnants of the catastrophic 1883 Krakatau eruption, every major change is being watched closely. However, authorities have reported no imminent tsunami threat from the current activity. In this video, we break down what is happening at Anak Krakatau, how high the ash cloud really reached, why volcanic ash is so dangerous to aircraft, how far the plume traveled, and what scientists are watching for next.
