In Pictures: Indonesia’s Merapi volcano unleashes river of lava

Mount Merapi’s new eruption has set off its longest lava flow since the volcano’s danger level was raised in November.

The Mount Merapi volcano on Indonesia’s Java island has spewed searing ash and other volcanic debris that poured down its slopes on Wednesday, the country’s geological agency said.

Pyroclastic flows – a fast-moving mixture of extremely hot rock fragments, gas, and ash – blasted from the volcano for four hours in the early morning, according to the Research and Development Center for Geological Disaster Technology, which monitors the volcano.

There were no reports of casualties and the alert level remained at the second-highest level, it said.

This was Mount Merapi’s biggest lava flow since authorities raised its danger level in November, said Hanik Humaida, head of Yogyakarta’s Volcanology and Geological Hazard Mitigation Center.

Authorities in November had evacuated nearly 2,000 people living on the mountain in Magelang and Sleman districts on Java Island but most have since returned. There has been no new evacuation.

The alert was being maintained at the second-highest level and authorities told people to stay out of the existing 5-kilometre (3-mile) danger zone around the crater as the local administrations in Central Java and Yogyakarta provinces closely monitor the situation.


The 2,968-meter (9,737-foot) volcano is on the densely populated island of Java and near the ancient city of Yogyakarta. It is the most active of dozens of Indonesian volcanoes and has repeatedly erupted with lava and gas clouds recently.

Merapi’s last major eruption in 2010 killed 347 people.

Indonesia, an archipelago of 270 million people, is prone to earthquakes and volcanic activity because it sits along the Pacific “Ring of Fire,” a horseshoe-shaped series of seismic fault lines around the ocean.

Indonesia: Hundreds evacuated as Mount Merapi spews hot clouds

Indonesia’s Mount Merapi volcano spewed avalanches of hot clouds on Thursday morning as hundreds of residents were evacuated from its fertile slopes.

Lighter eruptions continued during the day, with a column of hot clouds rising 200 metres (656 feet) above the crater.

The initial eruption of pyroclastic clouds was obscured by fog over the mountain. The amplitude record and seismic recording data from Geological Disaster Technology Research and Development Center estimated the hot clouds spread less than 1km (0.6 miles) from the crater.

“Until now, the potential danger is not more than 5 km [3 miles],” chief of Yogyakarta’s Volcanology and Geological Hazard Mitigation Center, Hanik Humaida, said in a statement.


The geological authority had raised the alert level of Mount Merapi to the second-highest level in November after sensors picked up increasing activity. Tourism and mining activities were halted.

The 2,968-metre (9,737-foot) mountain is about 30km (19 miles) from the Yogyakarta city centre. About a quarter-million people live within 10km (6 miles) of the volcano, according to authorities in surrounding districts.

It spewed ash and hot gas in a column as high as 6km (4 miles) into the sky in June, but no casualties were reported.

Its last big eruption in 2010 had killed 347 people and caused the evacuation of 20,000 villagers.

Indonesia, an archipelago of more than 250 million people, sits on the Pacific “Ring of Fire” and is prone to earthquakes and volcanic eruptions. Government seismologists monitor more than 120 active volcanoes.
