Pilots from Qantas Airlines reported an eruption around 1600 on 27 June. A plume moved W and reached an altitude of about 6,000 m. However, the eruption was not visible in GMS satellite imagery.
Geologic Background. Ruang volcano, not to be confused with the better known Raung volcano on Java, is the southernmost volcano in the Sangihe Island arc, north of Sulawesi Island. The 4 x 5 km island volcano rises to 725 m across a narrow strait SW of the larger Tagulandang Island. The summit contains a crater partially filled by a lava dome initially emplaced in 1904. Explosive eruptions recorded since 1808 have often been accompanied by lava dome formation and pyroclastic flows that have damaged inhabited areas.
