JAKARTA — The alert level for Mount Anak Krakatau in the Sunda Strait was raised early Thursday amid increased volcanic activity.
With the increase in the alert level to siaga (watch), the danger zone has been expanded to a 5-kilometer radius from the crater from the previous 2-kilometer radius.
“Residents and tourists are prohibited from approaching the crater,” the Volcanology and Geological Hazard Mitigation Center (PVMBG) announced in a statement.
The agency said its monitoring posts had detected increased volcanic activity, as seen in small eruptions followed by ash fall that reached areas in nearby Cilegon and Serang, Banten.
“Residents are advised to wear face masks and eye protection while doing outdoor activities,” the agency said.
Previously, the National Disaster Mitigation Agency (BNPB) warned the public to stay 500 meters to 1 kilometer from the coast amid fears of another tsunami. A number of beaches in the province were struck by the Sunda Strait tsunami on Saturday night. As of Wednesday, the confirmed tsunami death toll reached 429.
