Background
Alutu volcano has multiple vents aligned along NNE-SSW and E-W fissures along a narrow graben between the two lakes. This silicic volcanic center lies along the regional Wonji Fault Belt and has produced abundant pumice-flow and pumice-fall deposits, along with lesser rhyolitic lava flows. Obsidian lava flows erupted from craters along the fissures have descended the flanks in all directions.Cinder cones, lava domes, phreatic explosion craters, and thermal springs are structurally controlled. The oldest known eruptions from Alutu produced the Hulo-Seyno Ignimbrite about 155,000 years ago. The latest eruptions produced obsidian flows and pumice breccias about 2000 years ago. Alutu eruptive products overlie recent basaltic lava flows to the west. Strong fumarolic activity continues, and the volcano has been the object of a geothermal exploration program.

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
