PVMBG memastikan erupsi Gunung Anak Krakatau saat ini tidak berpotensi memicu tsunami karena struktur fisik gunung belum cukup besar untuk mengalami keruntuhan mematikan seperti pada 2018 lalu, ketika tsunami dipicu oleh keruntuhan sebagian tubuh gunung ke laut dalam volume besar. Meskipun demikian, status gunung tetap Level III (Siaga) dan aktivitas erupsi mengalami penurunan dibanding dua hari sebelumnya.

Poin-Poin Utama

PVMBG confirms current eruption of Gunung Anak Krakatau will not trigger a tsunami.
The 2018 tsunami was caused by a large-volume collapse of the volcanic body into the sea.
Gunung Anak Krakatau's physical structure remains stable based on latest morphological mapping.
Post-2018 regrowth of the volcano remains relatively small and poses no collapse risk.
The crater's base shape shows no significant changes compared to previous mapping.
Gunung Anak Krakatau status remains at Level III (Siaga).
Coastal communities in Banten and Lampung are advised to remain vigilant.
Eruption activity decreased compared to two days prior.
From 00:00 to 06:00 WIB on September 6, 2026, 9 multi-phase earthquakes were recorded.
14 no-frequency earthquakes were recorded during the monitoring period.
2 blast earthquakes and 1 shallow volcanic earthquake were recorded.
Continuous tremor amplitude ranged from 8 to 45 millimeters with dominant amplitude around 15 millimeters.
Only one eruption event was recorded, lasting approximately 30 seconds.
Monitoring was conducted from Pos Pengamatan Gunung Anak Krakatau Pasauran, Banten.
