Mount Sinabung, an inactive volcano located in North Sumatra, Indonesia, erupted multiple times in late 2013, prompting evacuations of nearby villages. After being dormant for 400 years, Sinabung erupted in August 2010 and has had increasing activity since, including eruptions in September and October 2013 that forced the evacuation of over 3,500 villagers within 3 km of the volcano each time. The largest eruption was on November 3, 2013, when the volcano sent an ash plume 7,000 feet into the air, prompting another 1,500 people to evacuate within 3 km of the volcano. Indonesian authorities subsequently increased the alert level for Sinabung.
