2018 Eruption
An eruption occurred at Soputan volcano on 3 October 2018, five days
after a magnitude 7.5 earthquake hit central Sulawesi. Ash emissions
reached 25,000 ft altitude. Another eruption of Soputan occurred on
16 December 2018 with ash emissions reaching 28,000 ft altitude.
2016 Eruption
On 6th February 2016 ash reached altitude of 20,000 ft over summit
and extended 55 nautical miles southwest to an altitude of 13,000
ft.
2015 Eruption
Eruptions of Soputan volcano began on 3rd January 2015. On 6th
January ash emissions reached 27,000 ft. A 6.5 km exclusion zone was
placed around the volcano and the alert level raised to RED. During
a visit to Soputan volcano in January 2015 by John Seach, ash
emissions were observed rising to 20,000 ft altitude.
2012 Eruption
An increase in activity occurred at Soputan volcano during August
2012. Between 16-25 August 938 avalanches were detected seismically.
On 26th August an explosive eruption ejected incandescent material
into the air. The alert status at the volcano was raised from level
2 (waspada) to level 3 (siaga) on 26th August.
2011 Eruption
An explosive eruption began at Soputan volcano on 3rd July 2011. The
eruption send an ash plume 6000 m high. The airport at Manado was
closed for three hours following the eruption.
Eruptions occurred at Soputan volcano in Indonesia on 14th August
2011. The first eruption at 7:55 am produced an eruption column 1 km
above the summit. The second eruption at 9:27 am produced a column
1.2 km above the summit. The alert status at the volcano was raised
to level 3 (out of maximum 4) on 14th August. An 8 km exclusion zone
was placed around the volcano.
2008 Eruptions
An eruption occurred at Soputan Volcano on 6th October 2008.
Ash was emitted to a height of 1000 m. The nearest villages are 8 km
from the crater, and no evacuations were necessary. A lava dome has
continued to grow in the crater since 1991. Eruptions are usually
occurring from the lava dome. The volcano was increased to level 3
alert (Siaga), out of a maximum 4.
Soputan volcano in Indonesia erupted at 10 am
(local time) on 6th June, 2008. Pyroclastic flows were recorded
extending 4 km from the summit, and ash emissions reached 2 km
above the volcano. Between March and June 2008 there was an
increase in ground temperatures and elevated seismicity at the
volcano. During May there were 2 volcanic earthquakes per day. On
6th June there were 6 volcanic earthquakes, and volcanic tremor
was recorded.
2007 Eruption
On 14th August 2007 an eruption of Soputan sent ash to a height of
4.6 km. Residents near the volcano were reported to be wearing face
masks, but no evacuations occurred. The nearest village is 11 km
from the crater. On 25th and 30th of October, lava flowed 500-600 m
down the west flank. A 6 km exclusion zone was placed around the
crater.
1973 Eruptions
Phreatic eruptions occurred in 1973.
1947 Eruption
Eruptions occurred at Soputan volcano between 22-25 August 1947.
1915 Eruption
In 1915, activity migrated 575 m southeast to a second parasitic
vent, Aesoput Weru.
1901 Eruption
In 1901, activity switched from the summit to a parasitic vent on
the north-northwest flank and resulted in the eruption of several
lava flows and the building of a 150-m-high cinder cone, Aesoput.
