Photo taken on Jan. 11, 2016 shows volcanic ash spewing from Mount Sinabung during an eruption seen from Kuta Tengah village in Karo, North Sumatra, Indonesia. Mount Sinabung's volcanic activity has not entirely ceased after it rumbled back to life in 2013 when thousands of people living close to the volcano forced to flee their homes after it began erupting violently.
