Anak Krakatau Eruption Shuts Down Airports Across Indonesia

September 18, 2026

Anak Krakatau erupted for over 24 hours, sending ash up to 50,000 feet into the atmosphere.

The eruption disrupted air travel and air quality across a wide area, including Jakarta. The ash cloud forced eight airports to close, affecting nearly 3,000 flights and causing significant economic disruption.

Airports were shut down due to safety concerns over volcanic ash, which can damage aircraft engines. This led to widespread flight cancellations and delays.

Long-term exposure to volcanic ash can degrade air quality and pose health risks to residents in affected areas.

What are the immediate real estate and economic risks?

The eruption has caused a temporary but significant disruption to local economies, particularly those reliant on air travel. Real estate values near affected airports may drop due to increased risk perception.

Real estate values could decline.
