A volcano on Indonesia’s Sumatra island has erupted with incredible violence, spewing a gigantic column of ash into the surrounding countryside. The extraordinary eruption even blocked out the sun as it blanketed villages in soot.

Mount Sinabung spat the enormous ash cloud five kilometers into the air on Monday, during its second eruption in three days.

Eyewitnesses reported hearing thunderous rumbling and explosion sounds. Video footage from the scene shows a giant cloud of dense ash rising high into the sky after spilling out of the mountain in Karo, North Sumatra. (RT)
