Indonesia's Merapi volcano erupts, spews hot cloud

Indonesia's Merapi volcano erupted, spewing hot clouds up to seven kilometres.

The volcano located in Indonesia's Yogyakarta special region erupted around 12 p.m local time (0500 GMT) and a lava flow of 1.5 km was observed, Reuters reports citing the country's disaster management agency.

Residents in the nearby community have been warned to stop any activities in the danger zones, range between three to seven kilometres radius from the crater, the statement said.

The 2,963 metre-high (9,721 feet) Merapi is one of Indonesia's most active volcanoes and was already on the country's second-highest alert level.

An official at the local monitoring post, Yulianto said no residents have been evacuated.

"This has only been observed as one-time event, there have been 5-6 avalanches. If the coverage continues to increase and the distance is further than seven kilometres, it is likely that the residents will be recommended to evacuate," he said.

Located on the Pacific Ring of Fire, Indonesia has more volcanoes than any other country. Merapi last violently erupted in 2010, killing more than 350 people.
