Indonesia’ Sinabung volcano erupts, spews 5km giant ash cloud into the sky

A volcano in the Indonesia spewed a 5km giant ash cloud  into the sky on Monday in its second eruption in three days, emitting a thunderous noise and turning the sky dark.

Mount Sinabung, on the island of Sumatra’s eruption comes after more than a year of inactivity and was the second since Saturday, as authorities warned residents and tourists about possible lava flows.

Authorities have asked residents to stay outside of a 3 km radius of the volcano and to wear masks to minimise the effects of falling volcanic ash.

No casualties have been reported so far. Flight operations in the region have been suspended.

Sinabung, located in one of the world’s most volcanically active countries, had been inactive for centuries before it erupted again in 2010.
