Indonesia’s Geological Agency on April 24 raised the alert level for the erupting Mount Anak Krakatau volcano to level 3, requiring a danger zone of up to 5 kilometers (3.1 miles) as volcanic activity intensified.
According to the Center for Volcanology and Geological Hazard Mitigation (PVMBG), the volcanic mountain began spewing ash clouds towering 3,000 meters from the peak in the past three days.
Hendra Gunawan, head of the Volcanic Mitigation Division, said April 25 that the PVMBG is coordinating with the relevant authorities on the potential secondary hazard, citing the eruption of Mount Anak Krakatau in 2018.
The volcano’s massive eruption in 2018 triggered an underwater landslide, resulting in a tsunami that killed at least 430 people along the Sumatra and Java shores.
