It was the volcano's second big eruption since late last month, with its Oct. 24 explosion prompting the evacuation of more than 3,300 people.
In September, more than 15,000 people were forced to flee when Mount Sinabung rumbled to life after being dormant for three years.

The volcano's previous major eruption, in August 2010, killed two people and forced 30,000 others to flee. It caught many scientists off guard because it had been quiet for four centuries.
