On Friday, the eruption of Mount Merapi in Indonesia continued. The authorities had to stop tourism and mining on its slopes.

A volcano on the populous island of Java unleashed clouds of hot ash on Wednesday. Fast-moving pyroclastic flows – a mixture of rocks, lava and gas – moved 5 km down its slopes. It was the largest lava flow on Mount Merapi since November 2020, said Hanik Humaida, head of Yogyakarta’s Center for Volcanology and Geological Hazard Mitigation.

On Thursday, there were several dozen more eruptions. The lava river advanced another 2.5 km. No casualties were reported, but about 253 people were evacuated to temporary shelters.

Employees of the Indonesian Geology and Volcanology Research Agency said that residents of the slopes of Merapi were advised to keep a distance of 7 km from the mouth of the crater and be aware of the danger posed by lava.

Authorities have closed at least five tourist attractions located in a danger zone within 5 km of the crater and stopped mining along the rivers of the volcano. Activities outside the danger zone remained open.

Mount Merapi is the most active of the more than 120 active volcanoes in Indonesia and has erupted repeatedly with lava and hot gas clouds recently. The Volcanological and Geological Hazard Mitigation Center did not raise the alert level of Merapi, which was already the second-highest of four levels since the eruption began last November. The last major eruption of Merapi in 2010 killed 347 people and forced the evacuation of 20,000 villagers.
