Soputan

Stratovolcano · Indonesia · 1785m

The small Soputan stratovolcano, seen here from the west, was constructed on the southern rim of the Quaternary Tondano caldera in northern Sulawesi Island. The youthful, largely unvegetated Soputan volcano is one of Sulawesi's most active volcanoes. 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.

Geological summary

The 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 is the only active cone in the Sempu-Soputan volcanic complex, which includes the Soputan caldera, Rindengan, and Manimporok (3.5 km ESE). Kawah Masem maar was formed in the W part of the caldera and contains a crater lake; sulfur has been extracted from fumarolic areas in the maar since 1938. Recent eruptions have originated at 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.
