Last checked: 7 September 2026, 14:14 WIB. Conditions are changing quickly. Check official government, school, airline and airport updates again before making plans.
The Anak Krakatau eruption is no longer only an aviation story. Volcanic ash has affected air travel, changed school arrangements in Jakarta and prompted health authorities to ask people in affected areas to reduce unnecessary time outdoors.
For families and residents, the practical questions are simple: Should children go to school? Is it better to stay inside? Should you wear a mask outside? Can you still fly? And what happens if an unexpected disruption changes your work, move-in or relocation plans?
This guide brings those questions together in one place using the latest official information available when it was checked.
The Situation at a Glance
The impact is broader than airport closures, so it helps to look at travel, school and everyday activity together.
| Current snapshot Anak Krakatau remains at Level III (Siaga / Alert). PVMBG continues to monitor activity and advises people not to enter a three-kilometre radius around the centre of activity. Jakarta has moved all schools to distance learning (PJJ) from 7 September while the ash situation is being evaluated. Indonesia’s Ministry of Health has advised people in ash-affected areas to limit outdoor activity. If going outside is necessary, it advises using a mask and eye protection. As of the latest Ministry of Transportation update available when this article was checked, seven airports remained temporarily closed until 18:00 local time on 7 September. Atung Bungsu Airport had reopened at 09:00. |
Schools in Jakarta Have Moved to Distance Learning
The Jakarta Provincial Government announced that all education units in Jakarta would move to distance learning (PJJ) from Monday, 7 September because volcanic ash had reached parts of the city.
The policy applies as a safety measure while conditions are monitored. It does not mean school is cancelled: learning continues from home, and the city says the arrangement will be evaluated as the situation develops.
Parents should still check messages from their own school because class schedules, online platforms and practical arrangements can differ.
For families outside Jakarta, do not assume the same rule applies. Follow the local education authority and the individual school.
If You Do Not Need to Go Outside, Keep Outdoor Activity Light
Indonesia’s Ministry of Health has asked people in affected areas to limit outdoor activity and stay indoors when there is no urgent reason to go out.
If you do need to go outside, the ministry advises wearing a mask and glasses or other eye protection. Children, older adults, and people with chronic respiratory or cardiovascular conditions are among the groups that may need extra care.
This does not mean everyone needs to stop all normal activity everywhere. Ash exposure and air quality can vary by location and by time of day. The practical approach is to reduce unnecessary exposure and check local conditions before planning outdoor exercise, school runs, long walks or other non-essential activities.
In Jakarta, you can check local readings and activity guidance through the official Udara Jakarta air-quality platform.
For everyday plans
Consider moving outdoor exercise, playtime and non-essential errands indoors when ash or air conditions are poor.
If you must go out in an affected area, follow the current Ministry of Health advice on masks and eye protection.
If you develop significant or persistent symptoms, seek advice from a qualified healthcare professional rather than relying on a general article.
Work, Meetings and Appointments May Need More Flexibility
If your workplace, school visit, medical appointment or property viewing involves a long commute or extended time outdoors, confirm the plan before leaving home.
Companies and service providers may adjust schedules differently. A flight delay can also create knock-on changes to airport pickups, hotel bookings, handovers and meetings later in the day.
For anything time-sensitive, confirm the latest arrangement with the organisation involved rather than assuming the original schedule still stands.
What Is Happening at Anak Krakatau?
According to PVMBG via Indonesia’s Ministry of Energy and Mineral Resources, the roughly 25-hour continuous eruptive episode that began late on 4 September ended at 00:04 WIB on 6 September.
PVMBG has kept Anak Krakatau at Level III (Siaga). The Geological Agency continues to warn about hazards including ash, hot material and other volcanic activity.
In its 7 September update, the Geological Agency again advised people affected by ash to reduce outdoor activity or use a mask when outside, while maintaining the three-kilometre exclusion recommendation around the volcano.
Why Can Volcanic Ash Affect Jakarta and Flights?
The impact depends on where ash moves in the atmosphere, not simply on the distance from the volcano.
BMKG has been monitoring volcanic-ash movement at different altitude layers. Winds can carry ash toward different parts of Banten, Jakarta, West Java, Lampung and surrounding areas.
That is why conditions can change quickly. One district may feel relatively normal while another sees more visible ash or poorer air conditions. The same applies to aviation: ash can affect airport areas or flight paths even when the volcano itself is far away.
For aircraft, volcanic ash is a serious safety hazard. FAA guidance on volcanic ash explains that ash can damage engines and other aircraft systems.
Latest Airport and Flight Update
Flight disruption remains significant, and the airport list is changing as conditions are reassessed.
In the latest Ministry of Transportation update available when this article was checked, seven airports remained temporarily closed until 18:00 local time on 7 September. They were:
- Soekarno-Hatta International Airport, Tangerang
- Halim Perdanakusuma Airport, Jakarta
- Radin Inten II Airport, Lampung
- Husein Sastranegara Airport, Bandung
- Budiarto Airport, Tangerang
- Pondok Cabe Airport, South Tangerang
- Muhammad Taufiq Kiemas Airport, Pesisir Barat, Lampung
Atung Bungsu Airport in Pagar Alam, South Sumatra, which had also been closed, was reported operating normally again from 09:00 on 7 September.
The ministry also reported that, as of 09:00 on 7 September, the cumulative disruption since 5 September had affected around 2,300 flights and 270,337 passengers. Those figures may continue to change.
If an Airport Reopens, Your Flight May Still Be Delayed
An airport reopening does not instantly restore the airline network.
Aircraft may need inspection, and airlines still need to reposition aircraft and crews, rebuild schedules, restore slots and reconnect passengers whose journeys were disrupted.
A flight from an airport that was never closed can still be delayed if its aircraft, crew or connecting route is tied to an affected airport.
Before leaving home, check your specific flight directly with the airline. Do not rely only on a published airport reopening time.
What Passengers Should Do
Keep the travel checklist simple and current.
- Check your flight in the airline app, website, email, SMS or call centre before leaving for the airport.
- If you have a connection, check the full itinerary rather than only the first flight.
- Ask the airline which rebooking, refund or other options apply if your flight changes.
- Keep records of cancellations, schedule changes and additional travel costs in case they are needed for insurance or administration.
- Allow extra time after airports reopen because schedule recovery can continue for hours or longer.
Indonesia’s Directorate General of Civil Aviation has also advised travellers to monitor airline information and avoid going to affected airports during closure periods.
How Noble Asia Can Help When Plans Change Unexpectedly
It has been a messy few days for a lot of people.
A disruption like this rarely stays in one place. A handover moves. A school visit has to be rescheduled. An arrival date shifts. A unit sits empty while ash comes through the vents.
That part we can help with. Tell us what’s been affected and we’ll help put it back in order rescheduling viewings and appointments, adjusting arrival and move-in plans, coordinating between the property and design teams, or checking on a unit you can’t get to yourself.
For safety decisions, always follow the latest official government, airline, school and health updates.
Stay safe and stay informed.
