Towering Ash Clouds Fill the Sky as Indonesia's Mount Sinabung Volcano Erupts

More than 30,000 people have been evacuated.

Ominous smoke clouds filled Indonesia's skies after a volcano erupted Monday morning.

Mount Sinabung on the island of Sumatra spewed ash and clouds that stretched more than three miles in the air.

Approximately 30,000 people living near the volcano were ordered to evacuate ahead of the eruption, and the Volcanic Ash Advisory Center in Darwin, Australia, issued a “red notice” to airlines travelling in the area.

Officials said no one was hurt due to the volcano eruption, although Mount Sinabung, located on the "ring of fire," was responsible for multiple fatalities in 2016, 2014 and 2010.

Previously, the volcano was dormant for 400 years.
