Anak Krakatau Eruption Causes Major Travel Disruption in Indonesia

• In early September 2026, the Anak Krakatau volcano erupted for over 24 hours, sending massive plumes of gas and ash into the atmosphere.
• The activity led to the temporary closure of eight airports across Java and Sumatra, disrupting nearly 3,000 flights.
• The volcano has since returned to a less intense eruptive phase, though authorities maintain a high-level alert status.

Eruption Details

• On September 5, 2026, satellite sensors from the Landsat 8 and Suomi NPP missions captured the scale of the ash cloud, which reached altitudes of up to 15,000 meters to the west.
• Following the 24-hour explosive event on September 6, the volcano transitioned back to its typical Strombolian pattern, consisting of intermittent ash spurts.
• Airports began resuming standard operations by September 8, following the abatement of the primary explosive phase.

Impact on Population and Health

• Ashfall heavily impacted populated regions, particularly in Jakarta and parts of West Java.
• The Indonesian Humanitarian Coordination Platform (IHCP) warned of health hazards, noting that volcanic ash can irritate the respiratory tract, eyes, and skin.
• Experts clarified that this volcanic particulate is distinct from the smoke generated by peatland fires, requiring different public safety and protection measures.
