The Centre for Volcanology and Geological Hazard Mitigation (PVMBG) has provided clarification regarding the fluctuating activity of Mount Anak Krakatau. Observation post officer Anggi Nuryo Saputro confirmed that the active volcano's status has never reached Level IV or the highest Alert status (Awas) during its monitoring period.
Anggi referred to historical records from when a tsunami struck the Sunda Strait in late 2018. Despite the major disaster caused by the collapse of roughly 60 percent of the volcano's body at that time, Mount Anak Krakatau's volcanic activity status remained recorded at Level III (Siaga).
Furthermore, PVMBG highlighted the difference in the volcano's physical profile today compared to 2018. Following the massive collapse that reduced the volcano's elevation from 338 meters to 157 meters above sea level (masl), the potential tsunami threat is considered no longer as severe as in the past.
Based on expert studies, this drastic change in physical form serves as a key factor distinguishing the current level of tsunami risk. Nevertheless, observers remain vigilant given that eruptive activity continues to fluctuate over time.
To date, Mount Anak Krakatau's status remains set at Level III (Siaga). Officers noted that eruption intensity is highly dynamic; while seven eruptions were recorded a few days prior, no significant eruptive activity has been observed today.
