JAKARTA, Indonesia (AP) — Flights to and from Indonesia’s capital of Jakarta resumed early Tuesday after ash from a volcanic eruption forced a two-day closure that halted nearly 3,000 flights.

Soekarno-Hatta International Airport and Halim Perdanakusuma Airport serving Jakarta, Husein Sastranegara Airport in West Java’s Bandung city and two smaller airports in Banten province reopened just after midnight, Transportation Minister Dudy Purwagandhi said.

Three other airports remained closed until 10 a.m., including Radin Inten II Airport in Lampung on the southern tip of Sumatra island, despite improving conditions. Atung Bungsu Airport in Pagar Alam in South Sumatra province had resumed normal operations Monday morning.

“We are taking a conservative approach because wind direction is highly dynamic,” Purwagandhi said in a statement. “We want to ensure that volcanic ash has moved away from airports around Anak Krakatau.”

Although tests at several airports showed no traces of volcanic ash, the extended closures would allow time for inspecting and cleaning surfaces and equipment like runways, taxiways and aircraft that may have been exposed to volcanic ash, Purwagandhi said.

The continuous eruption of Anak Krakatau with lava fountains and loud booms ended Sunday but the volcanic island remained active Tuesday morning. Eruptions were reported at 5:08 a.m. and 5:34 a.m., though the height of the ash column could not be observed.

The airport closures Sunday and Monday disrupted nearly 2,961 flights, including 622 international services, and affected about 341,000 passengers.

The government also authorized schools in areas affected by volcanic ash to shift temporarily to online learning to reduce students’ exposure to ash.

Anak Krakatau is a volcanic island in the Sunda Strait between Indonesia’s main islands of Java and Sumatra. Its name means “child of Krakatau,” and the volcano is the offspring of the infamous Krakatau, whose monumental 1883 eruption triggered a period of global cooling.

An eruption of Anak Krakatau in 2018 caused a tsunami that killed at least 430 people in Sumatra and Java. Researchers believe volcanic activity triggered an underwater landslide and caused a large chunk of Anak Krakatau’s southwest slope to collapse and displace a large volume of water.

The volcano remained at Indonesia’s second-highest alert level since July, and authorities advised residents, tourists and fishermen to stay at least 3 kilometers (1.9 miles) from the active crater.
