Indonesia’s Centre for Volcanology and Geological Hazard Mitigation (PVMBG) raised Anak Krakatau to Level III (Siaga) on 2 July 2026, following increased eruptive activity and a series of ash explosions recorded over the preceding 72 hours. The alert is the second-highest in Indonesia’s four-tier system.

What Level III Means

Level III (Siaga) indicates elevated volcanic activity with the potential for significant eruption. Under this status, PVMBG has established a 5 km exclusion zone around the crater. No vessels or aircraft are permitted within this radius, and access to the island itself is prohibited.

The exclusion zone is enforced by the Indonesian maritime authority. Tour operators running Krakatau trips from Anyer, Carita, or Bandar Lampung have suspended departures to the volcanic islands until the alert level is reduced.

Practical Impact for Visitors

The most immediate impact is on organised day trips and overnight camping excursions to the Krakatau archipelago. These are a popular add-on for visitors staying along Java’s western coast or crossing between Sumatra and Java, and all current departures are suspended.

Travellers with pre-booked Krakatau tours should contact their operators directly. Most reputable operators in the area are offering rescheduling or refunds given that the suspension is beyond their control.

The rest of Banten province and the surrounding coastal areas — including the beach resorts at Anyer — are not within any restricted zone and are operating normally. There is no ash fallout currently affecting the coastal towns.

Monitoring and Updates

PVMBG updates activity reports daily via the MAGMA Indonesia platform. Alert levels can change quickly in either direction depending on seismic readings; a reduction to Level II would allow the exclusion zone to be narrowed.

Indonesia’s volcanoes are monitored in real time, and level changes are communicated through the tourism ministry and provincial authorities. We recommend checking current status with your tour operator before travel if you are planning a Krakatau visit.

Broader Safety Context

Anak Krakatau’s 2018 collapse and subsequent tsunami — which caused significant casualties along the Sunda Strait coastline — created much greater awareness of the need for exclusion zones during elevated activity periods. The current Level III protocols are more conservative than those in place before 2018, and authorities have been clear about enforcement.

For visitors based in Jakarta planning coastal trips or Sumatra crossings, this alert does not affect the main ferry routes or road access to the Anyer–Carita coast. Our safety guide has broader practical information for travel in Indonesia.

The situation is being actively monitored. Provided the exclusion zone is respected, the alert has no impact on the vast majority of visitor itineraries in the region.
