2019-21 Eruptions
Sinabung remains active in 2021. Eruption of Sinabung volcano occurred on 8 August 2020. Ash emissions reached altitude of 11,000 ft. This is the first eruption of Sinabung for more than a year. The volcano remained at level 3 alert (SIAGA) on a scale of 1 to max 4.
2013-14 Eruption
Eruption of Sinabung volcano in September 2013 sent ash to altitude
of 20,000 ft. An increase in activity has occurred at Sinabung
volcano, Sumatra suring the second half of November 2013. On 18th
November 2013 ash emissions reached altitude of 37,000 ft. On 24th
November Sinabung was raised to the maximum level 4 alert (awas).
Four centimetre diameter projectiles were ejected 4 kilometres from
volcano. A 5 km radius exclusion zone was placed around the volcano,
and 15,000 people evacuated.
During an expedition to Sinabung volcano, Sumatra in January 2014 John Seach observed eruptions. Pyroclastic flows were descending the southeast flank of the volcano with a runout distance of 5 km. On 14th January there were almost continuous pyroclastic flows. The eruption was accompanied by ash emission from two locations on the summit of the volcano. Pyroclastic flows were approaching close the the edge of the exclusion zone. Heavy ashfall occurred on the south and southwest of the volcano causing damage to crops.
2014 Fatalities
On 1st February 2014, at least 14 people were killed by a
pyroclastic flow inside the restricted zone at Sinabung volcano,
Indonesia. A large eruption sent the burning cloud into Sukameriah
village 2.7 kilometres from the volcano's crater. More victims are
suspected but rescue teams were prevented from entering the area due
to the risk of more pyroclastic flows.
2010 Eruption
Activity began at Sinabung volcano, on 27th August 2010 after a
millennium of inactivity. Six large explosive eruptions have
occurred at the volcano in the past month. These eruptions occurred
on August 27 at 18:30 pm, August 29 at 0:10 pm, August 30 at 06: 23
pm, September 03 at 04:38 and 17:59 pm, and September 7, at 0:23:37
pm. The largest explosive eruption occurred on September 7. Eruption
was accompanied by strong roar and rattled windows 8km from the
volcano. An eruption column 5000 m high drifted southeast. As of
September 22, 2010, activity was dominated by thick white gas
emission, rising an average height of between 50-100 m above the
crater.
Eruption 1200 years ago
Center for Geological Survey in Bandung has dated charcoal at
Sinabung volcano at 1200 years ago. Some pyroclastic flow deposits
have been estimated at 800-900 years ago.
