A powerful explosive eruption occurred at the volcano during 4-6 January. It began with a series of at least 4 powerful explosions between 20:50 on 4 Jan and up to the next morning, producing tall ash plumes that rose 4-6 km above the volcano and drifted north.
At least some of the explosions also triggered pyroclastic flows reaching the southern base of the summit cone. Moderately strong ash fall of 1-2 cm occurred in villages about 10 km to the NE of the volcano.
Apart from significant damage to farmland because of the ash cover, no injuries or damage to infrastructure were reported. The airport of Manado had to be closed for 2 days.
In the course of the second day (5 Jan), the activity at the volcano changed to violent lava fountaining from a fissure vent at the summit of the cone, producing lava flows that descended the cone. Activity ceased after around 6 January.

Activity remains elevated. An explosion produced an ash plume to 10,000 ft (3 km) altitude this morning. [details]

Background:

The small Soputan stratovolcano on the southern rim of the Quaternary Tondano caldera on the northern arm of Sulawesi Island is one of Sulawesi's most active volcanoes.  The youthful, largely unvegetated volcano rises to 1784 m and is located SW of Sempu volcano.  It was constructed at the southern end of a SSW-NNE trending line of vents.  During historical time the locus of eruptions has included both the summit crater and Aeseput, a prominent NE-flank vent that formed in 1906 and was the source of intermittent major lava flows until 1924.
