Yogyakarta: One of the world’s most active volcanoes, Indonesia’s Mount Merapi, has spewed ash into the sky as lava streamed down from its crater.
Although the authorities did not warn people on Thursday evening, the activity at Merapi raises concern.
Local residents were previously advised to stay outside a five-kilometre (three-mile) no-go zone around the crater near Indonesia’s cultural capital Yogyakarta.
According to reports its last major eruption in 2010 had killed more than 300 people and forced some 280,000 others to evacuate.
The report said it was Merapi’s most powerful eruption since 1930, which killed some 1,300 people, while another explosion in 1994 took about 60 lives.
Indonesia has more than 17,000 islands and islets with nearly 130 active volcanoes.
The archipelago sits on the Pacific Ring of Fire that causes frequent quakes and major volcanic activity.
