Indonesia's Mount Merai erupted on Sunday (June 21) sending clouds of grey ash 6,000 meters into the sky.

The footage was recorded by Ruwandi, a local resident who was cycling just several kilometers away when the volcano erupted.

Indonesia's Mount Merapi, one of the world's most active volcanoes, erupted twice on Sunday, sending clouds of grey ash 6,000 meters into the sky, the country's geological agency said.

The two eruptions lasted around seven minutes, according to the agency, and prompted local authorities to order residents to stay outside a three-kilometer no-go zone around the rumbling crater near Indonesia's cultural capital Yogyakarta.

He video was recorded by Ruwandi, a local resident who was cycling just several kilometers away from the crater when the volcano erupted without a prior warning.
