Sultan HB X Reveals Method to Clean Krakatau Volcanic Ash, Citing Mount Kelud Eruption

The Governor of the Special Region of Yogyakarta, Sri Sultan Hamengku Buwono (HB) X, has reminded the public not to handle volcanic ash haphazardly amidst the potential spread of eruption materials from Mount Anak Krakatau. Yogyakarta’s experience facing ashfall during the 2014 eruption of Mount Kelud serves as a vital lesson in addressing the current threat of volcanic ash.

The Sultan stated that volcanic ash possesses different characteristics compared to ordinary sand or dust. Its extremely fine and sharp particles can become airborne again if cleaned using improper methods, thereby increasing the risk of inhalation by the community.

“Volcanic ash contains dangerous, sharp materials,” he said during an interview at the Kepatihan Complex in Yogyakarta.

Although the volcanic ash from Mount Anak Krakatau is not yet reported to have reached Yogyakarta, the Sultan urged the public to remain cautious. He noted that managing ash requires more than just attempting to remove it from surfaces, as the material can easily re-disperse into the air.

“This fine ash can go anywhere. There is a significant risk for residents who might inhale it,” he remarked.

The Sultan also warned the public against using fans or air blowers to clean volcanic ash. Such methods have the potential to cause fine particles to fly back into the surrounding environment.

“Therefore, it is better to use masks for now,” he added.

According to the Sultan, the experience during the Mount Kelud eruption demonstrated that volcanic ash is not as easily managed as sand. The extremely fine nature of the material allows it to spread and move according to environmental conditions.

“With sand, you can simply sweep it away, but this is not like that,” he said.

In addition to the issue of ash exposure, the Sultan also highlighted the safety of residents when cleaning accumulated material from rooftops. He expressed concern that those without experience in handling ashfall might suffer accidents while attempting to clean their roofs.
