PVMBG recommendations
1. Masyarakat di sekitar Gunungapi Anak Krakatau dan pengunjung/wisatawan/pendaki tidak diperbolehkan memasuki dan melakukan kegiatan di dalam wilayah radius 5 km dari pusat erupsi Anak Krakatau. 2. Masyarakat di sekitar Gunungapi Anak Krakatau dan pengunjung/wisatawan tidak diperbolehkan memasuki dan melakukan kegiatan di dalam wilayah radius 1 km dari pulau baru di sektor barat laut dan tenggara Gunungapi Anak Krakatau. 3. Meningkatkan kewaspadaan terhadap ancaman bahaya lontaran batu pijar, hujan abu lebat, aliran lava, dan potensi erupsi sekunder yang ditimbulkan oleh kontak panas lava, baik dengan air laut maupun air hujan dalam radius 5 km dari pusat erupsi Anak Krakatau. 4. Masyarakat di wilayah pantai Provinsi Banten dan Lampung harap tenang dan jangan mempercayai isu-isu tentang erupsi Gunungapi Anak Krakatau yang akan menyebabkan tsunami, serta dapat melakukan kegiatan seperti biasa dengan senantiasa mengikuti arahan BPBD setempat. 5. Untuk mengetahui informasi dapat menghubungi Pusat Vulkanologi dan Mitigasi Bencana Geologi, Badan Geologi (022) 7272606 di Bandung (Provinsi Jawa Barat) atau Pos Pengamatan Gunungapi Krakatau (0254) 651449 atau 085846324506 di Pasauran (Provinsi Banten).

Eruption with volcanic ash cloud at 0445 UTC (1145 local).
Best estimate of ash-cloud top is around 2102 FT (657 M) above sea level or 1600 FT (500 M) above summit. May be higher than what can be observed clearly. Source of height data: ground observer.
Eruption and ash emission is continuing. Eruption recorded on seismogram with maximum amplitude 70 mm. Tremor recorded on seismogram with maximum amplitude 70 mm.
