On Sunday, Anak Krakatoa, which means "Child of Krakatoa", erupted and threw a huge cloud of ash into the sky.
The authorities also expanded the exclusion zone aroundcrater and warned nearby residents to wear masks outside due to the large ash plume. The volcano threw it over the strait separating the islands of Java and Sumatra.
“We upgraded the status of Anak Krakatau from second tothird level and recommended that no one be allowed to approach the active crater closer than five kilometers in radius,” Hendra Gunawan, head of the Center for Volcanology and Geological Hazard Mitigation, said at a virtual press conference.
The crater also recorded a significant spike in carbon dioxide emissions, the official said. On April 15, it emitted 68 tons of CO₂, and a week later, on April 23, it emitted more than 9,000 tons.
There were no reports of evacuations on nearby islands. Also, the busy sea route from the port of Merak in Java to the port of Bakaueni in Sumatra was not affected.
The volcano has been sporadic in activity since then.since, at the beginning of the last century, it emerged from the sea in the caldera formed after the eruption of Krakatoa in 1883. This disaster was one of the deadliest and most devastating in history, killing approximately 35,000 people.
Anak Krakatoa last erupted in 2018, triggering a tsunami that killed 429 people and left thousands homeless.
