Mount Sinabung is an active stratovolcano that is located in Indonesia on the island of Sumatra. This volcano reaches an elevation of 8,071 feet and is part of the Sunda Arc, which was created when the Indo-Australian Plate moved underneath the Eurasian Plate. It holds four volcanic craters, although only one is active, and many hardened lava flows along its edges.
Mount Sinabung has erupted several times between 1912 and 2014, since its last known eruption in 1600. In 2010, the volcano produced a small eruption that included an ash plume and lava flows. Residents who had been evacuated prior to the eruption returned to their homes a few dews later. Two more eruptions occurred in September of 2010, only one day after the residents had returned. The volcano produced a large eruption a few days later, causing a mixture of ash and water to coat villages and trees. The government released their highest-level warning, evacuating 17,500 people, and one man lost his life due to respiratory issues that flared during the evacuation.
Mount Sinabung erupted a third time since its activity began in 2010 in November of 2013, producing a 4.3 mile high ash column that forced the evacuation of hundreds of nearby villagers. Prior to the eruption, over 14,000 people were evacuated from the area. Six days after the eruption began, a lahar flowed down the slopes of the volcano and it has released one or two ash plumes each day since this time. The most recent eruption occurred on January 4, 2014 and was reported to have caused damage to animal life and villages surrounding it.
