Indonesia’s Mount Illy Levotolok rose to water on Sunday and closed a flight warning and local airport 2.5 miles (4 km) away in the sky.
There were no reports of injury or damage from the explosion in a remote part of the southeast Asian archipelago. But officials raised the volcano’s warning status to its second-highest level as they warned of possible lava flows.
The 1.2-mile no-go zone around the crater was also extended by 2.5 miles, while flights were advised to clear the area as volcanic ash rains occurred at Vunopitu Airport in eastern Nusa Tenggara, which was temporary. The form was closed.
“People are advised not to carry out any kind of activities within a radius of 4 km from the crater.”
Indonesia is home to about 130 active volcanoes due to their position on the Ring of Fire, a belt of tectonic plate boundaries in the Pacific Ocean spur where seismic activity often occurs.
In late 2018, the Anac Cretau, a volcano in the Strait between Java and Sumatra islands, erupted and caused an underwater landslide that killed more than 400 people, sparking a tsunami.
