An aerial view shows a volcanic island erupting, with a massive billowing plume of white and gray ash or steam rising above the dark cone. Turbulent waves and pale froth surround the shoreline, with ocean visible on the left and dark land extending to the right.

Summary

An eruption of Indonesia’s Anak Krakatau volcano sent ash clouds across Java, Sumatra and surrounding airspace, forcing the closure of eight airports, including Jakarta’s major Soekarno-Hatta and Halim Perdanakusuma facilities. Depending on the reporting time, between 170,000 and 270,000 passengers were affected and roughly 1,500 to 2,300 flights were canceled, delayed or disrupted. Although the main continuous eruption ended after about 25 hours, authorities warned that further activity remained likely, extending airport closures and creating uncertainty for travelers and airlines. No deaths, injuries, evacuations or tsunami were reported, but schools in ash-affected areas shifted to remote learning, residents were advised to wear masks, and a three-kilometer exclusion zone remained around the volcano. The event also revived memories of Anak Krakatau’s 2018 collapse, which triggered a deadly tsunami.

Key Points

  • Volcanic ash from Anak Krakatau forced eight Indonesian airports to close and disrupted between 1,500 and 2,300 flights, stranding up to approximately 270,000 passengers.
  • Ash plumes reached altitudes of about 20,000 to 50,000 feet and spread over Jakarta, Java, Sumatra and nearby airspace, creating continuing risks for aircraft operations.
  • Authorities maintained airport closures and a three-kilometer exclusion zone because the volcano remained on Alert status and could erupt again.
  • No casualties or tsunami were reported, while schools moved online and residents were urged to use masks to reduce exposure to volcanic ash.
  • The eruption recalled Anak Krakatau’s 2018 partial collapse and tsunami, as well as the catastrophic 1883 Krakatoa eruption.

Indonesia volcano eruption leaves 270,000 stranded as airports extend closure - BBC News

A volcanic eruption at Anak Krakatau has stranded about 270,000 passengers across Indonesia after more than 2,000 flights were cancelled or disrupted and several airports suspended operations for a second day. The volcano, located in the Sunda Strait roughly 150km from Jakarta, began erupting late on Friday, producing lava fountains and ash clouds that spread toward Jakarta, Lampung and western Java. Ash reached altitudes of up to 6,000m on the Java side and 15,000m on the Sumatra side, creating continuing risks for aviation. Jakarta’s Soekarno-Hatta International Airport and Halim Perdanakusuma Airport extended their closures after volcanic ash remained in the surrounding airspace. Flights were expected to resume at 23:59 on Monday, although Transport Minister Dudy Purwagandhi said the timing depended on changing weather conditions. Authorities were conducting regular tests to determine whether the ash cloud was expanding or dispersing. Passengers described crowded terminals, repeated schedule changes and uncertainty over alternative transport. One traveller took two trains overnight to reach Jakarta, while a Malaysian honeymooning couple said they had been told their return flight to Kuala Lumpur might not operate until 11 September. Other travellers faced delays after plans to visit Ujung Kulon National Park were cancelled because of heightened volcanic alerts. Indonesia’s Geological Agency warned that the likelihood of further eruptions remained high. Authorities established a 3km exclusion zone around the crater and prohibited ships from entering the equivalent zone in the Sunda Strait. They also confirmed that there was no tsunami warning associated with the latest activity. Anak Krakatau emerged from the caldera created by the 1883 Krakatoa eruption and has remained intermittently active. Its partial collapse in December 2018 triggered a tsunami that killed more than 400 people and injured or displaced thousands along the coasts of Java and Sumatra. The current eruption has caused major travel disruption but no tsunami has been reported.

Indonesia volcano eruption cancels hundreds of flights at major airport hub - CBS News

An eruption of Anak Krakatau in Indonesia’s Sunda Strait caused widespread flight cancellations and airport closures on Sunday after volcanic ash drifted across western parts of the country. AirNav Indonesia closed airspace around Jakarta’s Soekarno-Hatta and Halim Perdanakusuma airports, as well as six other airports, including Radin Inten II Airport in Lampung. By Sunday evening, the closures had affected approximately 170,000 passengers and resulted in 1,558 canceled flights, including 963 at Soekarno-Hatta. The airports were scheduled to remain closed until 8:59 a.m. Monday, although officials warned that disruptions could continue as airlines worked to restore aircraft rotations, fleet availability and terminal capacity. No deaths, injuries or evacuation orders were reported. The nearest settlement is more than 10 miles from the volcano, but authorities advised people to remain at least two miles away from the crater. Satellite monitoring identified two ash clouds: one reached 20,000 feet and moved northeast over Jakarta and surrounding areas, while another rose to 50,000 feet and spread across parts of Banten, Lampung and Bengkulu, the southern Sunda Strait and waters west of Sumatra. Indonesia’s Geological Agency said Anak Krakatau had been active since Friday and that Sunday’s 30-second eruption was the strongest since activity intensified in July. Officials said the continuing eruptions indicated a persistent supply of magma and volcanic gases, but they could not predict whether a larger eruption would follow. Hazards include ash, concentrated volcanic gases and hot rocks near the crater. Schools in ash-affected areas were authorized to shift temporarily to online learning. The eruption also revived memories of the volcano’s history. Anak Krakatau, or “child of Krakatau,” emerged from the site of the catastrophic 1883 Krakatau eruption. A 2018 eruption triggered an underwater landslide and tsunami that killed at least 430 people in Sumatra and Java and reduced the island to about one-quarter of its former size.

Volcano eruption disrupts hundreds of flights at Jakarta airport

The eruption of Indonesia’s Mount Anak Krakatau caused widespread aviation disruption across the Jakarta region and neighboring countries over the weekend. Volcanic ash temporarily closed Jakarta’s Soekarno-Hatta International Airport, with airport suspensions extended several times on Sunday and cancellations continuing into Monday. At least 373 flights were affected by 10:35 a.m. Sunday, including 202 flights at Soekarno-Hatta, where 167 were canceled. The airport is Southeast Asia’s second-busiest by scheduled airline seat capacity this month, with approximately 3.24 million seats, amplifying the regional impact of the disruption. Mount Anak Krakatau entered a continuous eruptive phase at 11:07 p.m. local time Friday. According to Indonesia’s Ministry of Energy and Mineral Resources, the activity continued for about 25 hours before ending at 12:04 a.m. Sunday. Despite the end of the continuous eruption, authorities said volcanic activity remained elevated and warned that the potential for additional eruptions was still high. Ash was detected over Jakarta and nearby areas, reaching altitudes of up to 20,000 feet while moving east and 50,000 feet while moving west. The ash cloud extended as far as the Indian Ocean, creating continued risks for aircraft operations. Singapore Airlines canceled nine flights between Singapore and Jakarta scheduled for Monday, while its budget carrier Scoot also canceled flights on the route. Authorities warned of possible incandescent rocks, heavy ashfall and lava flows if continuous eruptions resume. Anak Krakatau remains at Level III, or “Alert,” and a three-kilometer exclusion zone remains in place around the volcano.

Video. Passengers face flight chaos in Indonesia after Anak Krakatau eruption | Euronews

An eruption of Anak Krakatau has caused widespread disruption to air travel in Indonesia, with volcanic ash forcing the closure of eight airports and leaving more than 268,000 passengers stranded. Approximately 2,300 flights have been cancelled or halted, prompting large crowds at Soekarno-Hatta Airport in Tangerang, where passengers queued at counters to seek refunds and information. Airport monitors displayed extensive cancellations as travellers dealt with the continuing uncertainty. The disruption affected airspace around Jakarta and other cities after ash from the volcano spread across parts of Java and Sumatra. Indonesia kept several airports closed on Monday while authorities monitored the situation. Schools in affected areas also shifted to remote learning to reduce exposure to volcanic ash and associated health risks. The Geological Agency said Anak Krakatau’s eruption lasted approximately 25 hours and ended on Sunday, but warned that the volcano remains active and could erupt or emit ash again in the coming days. Authorities therefore continued to treat the aviation situation cautiously despite signs that the eruption was easing. The event highlights Indonesia’s exposure to volcanic hazards. The country lies on the Pacific Ring of Fire and has more than 120 active volcanoes. The immediate effects described in the report are primarily transportation disruption, passenger displacement, airport closures and temporary changes to schooling, rather than reported casualties. The article focuses on scenes at the airport and official assessments of the volcano’s continuing activity.

Volcano in Indonesia erupts, canceling hundreds of flights and stranding thousands | Euronews

Mount Anak Krakatau in Indonesia erupted over the weekend, sending lava and large ash plumes into the air and disrupting air travel across the region. The volcano is located approximately 150 kilometres from Jakarta. Ash drifting into nearby airspace led to the suspension of operations at eight airports and the cancellation or disruption of hundreds of flights, leaving more than 170,000 passengers stranded. Jakarta’s Soekarno-Hatta International Airport, the capital’s primary airport, was among the facilities affected. Three other airports, including Halim Perdanakusuma, also extended their closures until 6 p.m. local time on Monday. Halim handles both commercial and military flights. Airport operator Angkasa Pura advised passengers to monitor their flight status directly with their airlines, citing increasing activity at Mount Anak Krakatau. Indonesia’s national geology agency said the possibility of additional eruptions remained high through Monday morning. The closures were intended to limit the risks posed by volcanic ash, which can threaten aircraft operations and visibility. Mount Anak Krakatau has been intermittently active since it emerged from the sea within the caldera created by the catastrophic 1883 eruption of Mount Krakatau. Its activity has previously produced deadly consequences. In 2018, a partial collapse of the volcano triggered a tsunami that killed 429 people and displaced thousands. The latest eruption caused significant travel disruption but the article does not report any deaths or injuries connected to the current event.

Eight Indonesian airports remain shut as flights cancelled due to volcanic eruptions | The National

Eight Indonesian airports, including Jakarta’s main airport and another airport serving the capital, remained closed on September 7 because volcanic ash from Mount Anak Krakatau was creating unsafe flying conditions. The volcano, located between Java and Sumatra, began erupting late on Friday, sending ash across Jakarta and nearby areas and disrupting air travel. Indonesia’s Transport Ministry said approximately 170,000 people had been affected by flight cancellations. Jakarta’s main airport was expected to remain closed until 6 p.m. local time, although officials said the reopening schedule was uncertain because of changing weather conditions. Transport Minister Dudy Purwagandhi said seven additional airports, including those serving the provinces of Lampung and West Java, would remain closed until at least 8:59 a.m. The closures were imposed as a safety measure because volcanic ash can threaten aircraft operations and visibility. Indonesia’s volcano monitoring agency recorded another Anak Krakatau eruption at 8:23 p.m. on Sunday and warned that the likelihood of further eruptions remained high. The country’s meteorological agency, BMKG, reported that ash had reached altitudes of up to 20,000 feet on the Java side and 50,000 feet on the Sumatra side, affecting parts of Banten province as well. Authorities advised residents to wear masks outdoors to avoid inhaling ash. Schools in Jakarta and Lampung were instructed to switch to remote learning because of potential health risks. The article places the event in the broader context of Indonesia’s location on the Pacific Ring of Fire, where earthquakes and volcanic eruptions are common. It also recalls that Anak Krakatau emerged from the site of the volcano formerly known as Krakatoa, whose 1883 eruption caused deadly tsunamis and killed more than 36,000 people.
