Five Indonesian airports resume flights after ash cloud clears

Al Jazeera reported that five Indonesian airports have reopened after crews cleared volcanic ash from runways and navigation equipment, ending a disruption that grounded thousands of flights across the archipelago. The airports, located in the regions most affected by the recent ash fall, were closed for several days while emergency teams worked around the clock to restore safe operating conditions.

The ash plume originated from an eruption of a volcano in East Java, which spewed fine particles into the atmosphere and settled on critical airport infrastructure. Aviation officials warned that even a thin layer of ash can erode turbine blades and obscure pilot visibility, prompting the precautionary shutdown. By the time the ash was cleared, airlines had canceled or delayed more than 2,000 scheduled departures, leaving passengers stranded and cargo shipments delayed.

Indonesia sits on the Pacific Ring of Fire, home to over 130 active volcanoes. Historically, eruptions have repeatedly forced airport closures, most notably the 2010 Mount Merapi event that halted operations at Yogyakarta’s Adisutjipto Airport. The country's civil aviation authority maintains strict protocols for ash monitoring, often coordinating with the Meteorology, Climatology, and Geophysical Agency to issue real‑time alerts. When ash concentrations exceed safe thresholds, runways are sealed off and flights are rerouted or suspended to protect aircraft and passengers.

The recent reopening is expected to ease pressure on airlines that have been scrambling to rebook passengers and recover lost revenue. Airport operators are now conducting additional inspections to ensure no residual ash remains on taxiways or in air‑conditioning systems, a step that can add several hours to the resumption process. Travelers who were affected are being offered vouchers or refunds, though the exact compensation policies vary by carrier.

Experts note that as climate change intensifies weather patterns, volcanic ash events may become more frequent and harder to predict, underscoring the need for robust contingency planning in the aviation sector. For now, the restored airports will serve as critical hubs for domestic and international travel, helping to restore normalcy to Indonesia’s bustling air network.
