The event took place shortly after 11:30 am (local time) and was observed by from the volcano observatory. It had been preceded by a significant increase in seismicity during the past days since Wednesday. According to the local report, a rock avalanche (but apparently no pyroclastic flow) traveled down the western side of the dome, reaching a length of approx. 500 m.

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.
