A strong eruption is occurring at Soputan volcano on North Sulawesi. Local news report that the volcano erupted a column of ash ("ash and smoke") of 5 km height earlier today (Sunday, 3 July). The Darwin VAAC even reports an ash plume at FL 460 (46,000 ft, ca. 14 km), which would be in fact indicating a major eruption. The ash plume is extending ca. 300 km to the west. [mehr]

A new small eruption took place at the lava dome of Soputan volcano on 6 October. Ash explosions produced plumes rising to 2.8 km (9,200 ft) a.s.l. and were accompanied by Strombolian activity that ejected incandescent material 50-150 m above the crater. On 7 October, white plumes rose to altitudes of 2.3-3.3 km (7,500-10,800 ft) a.s.l. Incandescent material was again ejected 50-150 m from the crater. Incandescent rockfalls traveled 500 m W. The next day, plumes rose to an altitude of 2 km (6,600 ft) a.s.l. and in the following days, the activity decreased. ... [mehr]

CVGHM reported that white and gray plumes from Soputan on 25, 26, 30 and 31 October rose to altitudes of 1.8-3.3 km. A lava flow traveled between 500-600 m down the W flank on 25 October. The Alert Level remained at 3 and villagers and tourists are advised not to go within a 6 km radius of the summit. [mehr]
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.
