Soputan volcano (North-Sulawesi, Indonesia): strong explosion, ash to 23,000 ft

A larger explosive-effusive eruption was reported to have occurred about two hours ago (10:15 UTC). At 11:45 UTC, Darwin VAAC issued alerts to aviation about an ash plume that had risen to estimated 23,000 ft (7 km) altitude and has been drifting NW. Aviation color code was immediately raised to RED.
Images and videos of the eruption at night showed that lava fountains from a fissure at the summit crater were feeding a flow on the cone's NW slope.
According to a local newspaper article, there were two eruptions today: a presumably smaller one (which did not cause any alerts) in the morning at 10:00, and a "terrific" eruption at 18:15 local time (or 10:15 GMT), which sent a large ash plume into the sky. Ash fall was reported from the areas at the feet of the volcano, but there seems not to have been any damage reported.
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. ... read all
The volcano is calm at the surface, but seismic activity shows it is at unrest and might erupt again soon. read all
Activity continues at the volcano, but has been decreasing. read all
A new explosive eruptive phase occurred this morning, producing an ash plume that rose 4.5 km from the volcano's summit and pyroclastic flows that traveled 2.5 km. ... read all
The eruption continues with an active viscous lava flow on the upper western flank. Occasional explosions such as this morning produce ash plume that rise to 3-4 km altitude, i.e. 1.5-2 km above the volcano. ... read all
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.
