Badan Geologi: Anak Krakatau 8 Kali Erupsi saat Penerbangan Dibuka
Badan Geologi mencatat delapan kali erupsi Gunung Anak Krakatau pada Selasa (8/9) dengan durasi singkat 10-15 detik dan sebaran abu vulkanik tidak melebihi radius 3 kilometer, sehingga zona aman tetap 3 km dari pusat aktivitas. Status gunung masih di Level III (Siaga) dan kini memasuki fase Strombolian dengan amplitudo erupsi kecil dan durasi pendek, sementara pergerakan seismik disebut menurun sejak 5 September. Meski ancaman abu vulkanik masih ada tergantung arah angin dan intensitas erupsi, penyebarannya diprediksi tidak terlalu jauh selama masih dalam fase Strombolian.
Poin-Poin Utama
- Badan Geologi recorded 8 eruptions of Mount Anak Krakatau on Tuesday (8/9).
- Each eruption lasted 10 to 15 seconds.
- Ash spread did not exceed 3 kilometers from the eruption center.
- Safe radius zone remains set at 3 kilometers from the activity center.
- Mount Anak Krakatau is currently at Level III with 'Siaga' (Watch) status.
- The volcano has re-entered the Strombolian phase.
- Strombolian phase is the normal character of Mount Anak Krakatau.
- Vulkanic ash threat still exists as a potential hazard.
- Ash spread depends on wind direction and air column (plume).
- Ash spread also depends on eruption intensity.
- Seismic movement has decreased since September 5.
- Low-level volcanic activity remains recorded.
- Recorded activity is normal due to fluid movement inside the volcano.
- Eruption amplitude during this phase is not too wide or long.
- Eruption duration during this phase is only a few seconds.
