Gunung Anak Krakatau erupted on Thursday, September 10, 2026, at 09:10 Western Indonesia Time, according to the Regional Disaster Management Agency (BPBD) of Lampung Province. The eruption produced a seismic record with a maximum amplitude of 47 mm and lasted for 17 seconds, while visual letusan could not be observed due to local conditions.
Monitoring Data and Current Weather Conditions
According to observation data from MAGMA Indonesia under the Ministry of Energy and Mineral Resources (ESDM), weather conditions at the volcano are currently cloudy with winds weakening toward the northwest. Monitoring instruments recorded three Hybrid or Multi-Phase earthquakes with amplitudes ranging from 11 to 14 mm and lasting between 4 and 7 seconds, alongside one continuous tremor earthquake with amplitudes spanning 2 to 7 mm, dominated by a 3 mm reading.
BPBD Lampung updated the status of the event as finished following the 17-second activity.
Public Safety and Restricted Zones
BPBD Lampung and geological monitoring agencies urge local residents, visitors, tourists, and climbers to refrain from approaching Gunung Anak Krakatau or conducting any activities within a 3-kilometer radius of the active crater.
Previous volcanic activity from the mountain has caused widespread operational impacts on regional transportation networks. Coverage from CNBC Indonesia noted that earlier ash dispersal forced the temporary closure of eight airports, including Soekarno-Hatta International Airport in Banten and Halim Perdanakusuma Airport in Jakarta.
Additional closures affected Radin Inten II Airport in Lampung, Husein Sastranegara Airport in Bandung, Budiarto Curug Airport in Banten, Pondok Cabe Airport in Banten, Taufik Kiemas Airport in Pesisir Barat Lampung, and Atung Bungsu Airport in Pagar Alam, South Sumatra.
