Indonesian Volcano Erupts, Disrupting Flights and Air Quality

Topic: Earth Science

Anak Krakatau volcano in Indonesia erupted, sending ash high into the atmosphere. The eruption disrupted thousands of flights and worsened air quality across parts of the country.

A powerful eruption at Anak Krakatau volcano in Indonesia sent ash high into the atmosphere. This caused problems for people living nearby and for travelers.

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 it can also produce much more hazardous activity. In early September 2026, Anak Krakatau entered a prolonged explosive phase that lasted for more than 24 hours.

Satellites captured the eruption from space. They showed large amounts of gas and ash rising into the sky. The eruption disrupted air travel and contributed to poor air quality in several areas, including Jakarta.

The Indonesian Humanitarian Coordination Platform (IHCP) reported that communities east of Anak Krakatau were particularly affected. Volcanic ash can pose health concerns because it may irritate the respiratory system, eyes, and skin.
