Indonesia's volcanic eruption and haze test regional trust
On September 15, Mount Anak Krakatau erupted, sending ash 15 kilometers high and disrupting air travel across the region. Simultaneously, forest fires in Borneo caused haze that worsened air quality in neighboring countries, with asthma cases rising in Sarawak. The events underscore how domestic disasters can affect Indonesia's international credibility and require coordinated responses.
The eruption's scale was considerable, with ash reaching 15,000 meters and rumbling audible across 700 kilometers. Eight airports halted operations, stranding over 270,000 passengers, while domestic impacts included eye irritation and school closures. Simultaneously, Borneo's fires produced haze that pushed Manila's pollution beyond four times WHO limits and triggered a 259% spike in Sarawak asthma cases.
The haze carries corporate dimensions, as concessions linked to Singapore, Japan, and Malaysia contribute to the smoke. Indonesia's disaster agency must simultaneously deliver physical risk guidance, psychological reassurance, and reputational repair, per the ASEAN framework emphasizing timely information-sharing among regional bodies.
These overlapping crises could strain Indonesia's regional credibility, as neighboring states bear direct consequences from domestic events. Affected groups include stranded travelers, asthma sufferers in Sarawak, and communities facing disrupted schooling. How Indonesia communicates may shape ASEAN cooperation on disaster response, potentially influencing whether regional trust deepens through coordinated transparency or erodes, complicating future cross-border environmental management.
