Mount Sinabung (Indonesian: Gunung Sinabung) is a Pleistocene-to-Holocene stratovolcano of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia. Many lava flows are on its flanks and the last known eruption had occurred in the year 1600. Solfataric activity (cracks where steam, gas, and lava are emitted) were last seen at the summit in 1912, but no other documented events had taken place until the eruption in the early hours of 29 August 2010.[1][2]
Geology
Most of Indonesian volcanism stems from the Sunda Arc, created by the subduction of the Indian Plate under the Indo-Australian Plate. This arc is bounded on the north-northwest by the Andaman Islands, a chain of basaltic volcanoes, and on the east by the Banda Arc, also created by subduction.[3]
Sinabung is a long andesitic-dacitic stratovolcano with a total of four volcanic craters, only one being active.[4]

On 29 August 2010, the volcano experienced a minor eruption after several days of rumbling.[5] Ash spewed into the atmosphere up to 1.5 kilometres (0.93 mi) and lava was seen overflowing the crater.[5] The volcano had been inactive for centuries, the last previous eruption occurring in 1600.[5]
Indonesian authority response
Indonesian authorities were reported to have evacuated around 18,000 people from the region on and around the volcano.[6] The government issued the highest-level warning for the area, which was expected to remain in force for around a week, since scientists were unfamiliar with the characteristics of the volcano, due to it having been dormant for so long.[6] The government has also set up kitchens for refugees to have access to food, and have handed out 7,000 masks. [7]
Effects
The nearest towns to the volcano are Kabanjahe and Berastagi; there were no disruptions reported to air services at the regional airport, Medan's Polonia.[8] One person is reported dead from respiratory problems while fleeing his home.[9]
