The 8,070 ft volcano started to spew lava in 2010, 400 years after it was last active. For five years, the flow of lava caused the death of 17 people and covered the towns of Berkerah in 2013 and Sukameriah in 2014. The residents of six different towns had to leave their homes to save themselves from being burnt.
