Badan Geologi menyatakan episode erupsi menerus Gunung Anak Krakatau yang berlangsung 25 jam telah berakhir pada 6 September 2026, dan aktivitas vulkaniknya kembali ke karakteristik erupsi strombolian. Meski grafik RSAM menunjukkan tren penurunan, tingkat aktivitas gunung masih ditetapkan pada Level III (Siaga) dengan probabilitas letusan susulan dinilai masih tinggi. Badan Geologi melarang aktivitas dalam radius tiga kilometer dari kawah aktif dan mengimbau warga pesisir Banten serta Lampung tetap tenang serta mengenakan masker untuk mengantisipasi paparan abu.
