Indonesia’s Mount Sinabung erupted Monday, sending a column of volcanic ash more than 16,000 feet (3 miles) into the sky and dumped debris on nearby towns.
The volcano was inactive for four centuries until 2010. Then erupted in 2013 and 2016, and has since remained active.
You may want to turn off the sound on the following video. I find the music annoying.
