Prior to the 2005 eruption, Garbuna volcano was considered to be in the solfatara stage. The main features were the presence of boiling mud pools, hot springs and sulphur emitting vents. In 1985, a geological survey recorded Garbuna volcano as dormant, but potentially hazardous.
A recent looking blocky dacite lava flow at the summit of Garbuna suggests a recent eruption.
Eruptions at Garbuna volcano occurred on 11th March 2008. Ashfall and booming noises were heard at the volcano. On 17th March seismicity increased to a moderate level. Light gray ash emissions were visible at Garbuna volcano on 13th July 2008. Emissions reached 1km above the summit.
Eruptions resumed at Garbuna Volcano in Papua New Guinea on 23rd September 2008. A pale gray ash column was observed rising to 1000 m altitude. Sustained volcanic tremor was recorded at the volcano on 29th and 30th September 2008. Incandescent lava eruptions were observed in August 2008.
John Seach climbed to the summit of Garbuna volcano on 14th and 17th November 2005, four weeks after the first eruption in 1700 years. The eruption began with a felt earthquake on 16th October 2005. Jet-like, and rumbling noises were heard at the volcano, followed by ash emissions. A local resident notified Air Nuigini, because the the flight path into Hoskins airport passed over the volcano. Darwin Volcanic Ash Advisory Centre issued a warning notice to pilots. John Seach observed the summit region which contained a steaming crater, devastated trees, and fresh mud deposits. Continuous seismic activity was recorded while on the summit. Heavy rainfall caused a lahar down the western flank of the volcano.
