![]() ![]() 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. The Indonesian government was reported to have evacuated around 17,500 people from the region on and around the volcano. Government response Mount Sinabung, March 20, 2010. The force of the explosion could be felt 8 km away. On Tuesday 7 September, Mount Sinabung erupted yet again, its most powerful eruption since. The eruption came with earthquakes which could be noticed out to a 25.0 kilometres (15.5 mi) distance around the volcano. A second eruption occurred the same evening, around 6 p.m. Some hours before the eruption a warning had been issued through the volcanology agency, and most villagers were prepared to leave quickly. The sound was heard from 8 kilometres away. This eruption was the most intense so far, with ash spewed up into the atmosphere about 3.0 kilometres (1.9 mi) high. The first one happened at 4:45 a.m., local time, forcing more villagers to leave their houses – some of them had just returned the day before. On Friday 3 September 2010, two more eruptions were noted. Total erupted volume from 2010 to the end of 2015 was estimated at 0.16 km 3 dense-rock equivalent. ![]() Mount Sinabung erupted after a 400-year-long hiatus in August 2010, and has been continuously active since September 2013. Sinabung has a total of four volcanic craters, one of them being active currently. The Andaman Islands are on the North-Northwest bound of the arc while the Banda Arc is on the East. The 2,460 meter high andesitic-to- dacitic volcano comes from the Sunda Arc, which is created by the subduction of the Indo-Australian Plate under the Eurasian Plate. The summit crater of the volcano has a complex, longer form due to vents migrating on the N-S line. It is located in a relatively cool area on a fertile plateau with mountains bounding the north. Mount Sinabung is a Pleistocene-to-Holocene stratovolcano. Geology įurther information: List of volcanoes in Indonesia A major eruption began on 10 August 2020. The long eruption of Mount Sinabung is similar to that of Mount Unzen in Japan, which erupted for five years after lying dormant for 400 years. On 2 June 2015, the alert was again increased, and on 26 June 2015, at least 10,000 people were evacuated, fearing a major eruption. Between 20, the alert for a major event was increased with no significant activity. The volcano has recently claimed the life of at least 23 people in a number of events since 2014. Solfataric activities (cracks where steam, gas, and lava are emitted) were last observed at the summit in 1912 recent documented events include an eruption in the early hours of 29 August 2010 and eruptions in September and November 2013, January, February and October 2014. ![]() Many old lava flows are on its flanks and the last known eruption, before recent times, occurred 1200 years before present, between 740 - 880 CE. Mount Sinabung ( Indonesian: Gunung Sinabung, Karo: Deleng Sinabung ) is a Pleistocene-to- Holocene stratovolcano of andesite and dacite in the Karo plateau of Karo Regency, North Sumatra, Indonesia, 40 kilometres (25 mi) from the Lake Toba supervolcano.
