Yogyakarta: The most turbulent volcano in Indonesia erupts weeks on a densely populated island, spewing smoke and ash to the air and sends the flow of lava and gas to the slopes.
There were no victims reported.
Mount Merapi releases hot ash clouds at least seven times since Sunday morning, as well as a series of fast-moving pyroclastic flows, mixed stones, debris, lava and gas, said Hanik Humaida, who heads the city of Volcanology Yogyakarta and geological hazard mitigation center.
A roar could be heard a few kilometers away.
The eruption sent a heat gray of 1,000 m (3,280 feet) into the sky, and the burning gas cloud took up to 3 km on the slopes several times, said Geology and Research on Volcanology Indonesia told the website.
Humaida said the mountain had seen increased volcanic activity in recent weeks, with a dome of lava growing rapidly before partly collapsed on Sunday, sending rocks and ash flowing to the southwest side of the volcano.
Ash from the eruption enveloped several nearby villages and cities, he added.
The villagers who lived in the fertime fertime slopes were advised to stay 5 km from the crater mouth and realized the dangers caused by Lava, said the Geological Research Agency and Volcanology.
However, the fiery mitigation center and geological hazards did not increase the warning status of Merapi, which was at the second highest of four levels since it began to erupt last November.
Mount Merapi is the most active of more than 120 active volcanoes in Indonesia and has repeatedly erupted recently.
But the last Merapi eruption last was in 2010, when 347 people were killed.
The peak of 2,968 meters (9,737 feet) is near Yogyakarta, an ancient city of several hundred thousand people embedded in the large metro area.
The city is also the center of Javanese culture and the royal dynastic seat will return for centuries.
Indonesia, a nusantara 270 million people, vulnerable to earthquakes and volcanic activity because they sit through the “Ring of Fire” Pacific, a series of seismic fault lines in the form of horseshoes around the ocean.
