Several parts of Medan and Kualanamu International Airport in Deli Serdang regency, North Sumatra, have reportedly been blanketed by volcanic ash from Mt. Sinabung.
"The volcanic ash has reached the airport, but operations, take-offs and landings, were not disrupted," airport spokesman Dewandono Prasetyo Nugroho said on Wednesday.
Although covered by ash, the airport, according to Prasetyo, remains safe for flights, as visibility is still 3,000 to 4,000 meters. Meanwhile, the volcanic ash disrupted daily life in Medan, forcing residents to cover their faces with masks.
"It causes pain and discomfort, especially in the eyes and nose," said Elvida Sari, who had to use a mask when riding her motorcycle to work.
