People have been advised to stay indoors because of the ash fallout
Hundreds of flights have been suspended after an airport had to be closed because of the ash cloud caused by a volcanic eruption. Tens of thousands of passengers have been left stranded. 209 flights were suspended after ash from Anak Krakatau blew into the airspace near Jakarta’s Soekarno-Hatta International Airport on Sunday.
Soekarno-Hatta is the main airport in Indonesia. The volcano started erupting on Friday night and there were two more eruptions on Sunday. More than 22,000 people have been hit by the suspension of flights, which has hity major international routes.
There is no tsunami warning linked to the eruption in the Sunda Strait between Java and Sumatra. The health minister has urged residents to stay indoors and wear face masks.
Local newspaper Kompas said schools cancelled activities on Saturday after students reported eye irritations. Fishing vessels have also been grounded amid health concerns.
Resident Aldi Candra Prayogi told Kompas it felt like “small grains of sand had gotten into my eyes” and he is having to clear the path outside his home every five minutes.
Anak Krakatau emerged from the sea in 1927 inside the caldera formed by the catastrophic, climate-altering eruption of the original Krakatoa volcano in 1883.
Indonesia’s Geological Agency said the volcanic island located in Indonesia’s Sunda Strait between the main Java and Sumatra islands had shown signs of activity since Friday before erupting for 30 seconds at 3.53am.
CCTV footage showed lava flares from the volcano. No casualties were reported and no evacuation order was issued. The nearest settlement is more than 16 kilometres (10 miles) away, but authorities warned residents and visitors to stay at least three kilometres (2 miles) from the active crater.
Volcanic ash spread across parts of Jakarta and Lampung province on Sumatra’s southern tip, Indonesia’s centre for volcanology and geological hazard mitigation said. AirNav Indonesia closed airspace around Soekarno-Hatta and Halim Perdanakusuma airports in Jakarta, as well as four other airports, including Radin Inten II Airport in Lampung, because of volcanic ash.
By mid-afternoon, the closure had affected 516 flight movements, with 202 in Jakarta’s Soekarno-Hatta airport alone, affecting about 22,800 passengers, on Sunday. The airport was ordered closed until at least 5.30pm.
Indonesia’s directorate general of civil aviation said it was closely monitoring the eruption’s impact on air travel and co-ordinating with airlines, airport operators, air navigation services and the meteorology agency.
“Safety remains our top priority in every operational decision,” Lukman F Laisa, ministry of transportation director general of civil aviation, said in a statement.
He warned flight schedules could face cascading disruptions affecting aircraft rotations, fleet availability and terminal capacity as airlines work to restore operations.
The eruption also disrupted services at Bali’s I Gusti Ngurah Rai International Airport and at Medan.
Indonesia’s volcanology agency and the Darwin Volcanic Ash Advisory Centre identified two ash clouds using satellite imagery. One plume rose to 20,000 feet (6,100 meters) and drifted northeast over Jakarta, Banten, West Java and nearby waters. A second cloud reached 50,000 feet (15,200 meters) and spread over parts of Banten, Lampung and Bengkulu provinces, the southern Sunda Strait and sections of the Indian Ocean west of Sumatra.
Lana Saria, head of Indonesia’s geological agency, said activity at Anak Krakatau has intensified since July, with Sunday’s eruption the strongest during the current period of unrest.
The repeated eruptions indicate a continued supply of magma and volcanic gases beneath the volcano, she said, though officials cannot predict whether a larger eruption will occur.
“We continue to evaluate the volcano’s development based on all monitoring data, not solely on the number of eruptions or the height of the ash column,” Ms Saria said in a video briefing.
She said the main hazards include volcanic ash, high concentrations of gas and the ejection of hot rocks and other material around the crater area.
