Geological Background of Mount Benbow
Mount Benbow is part of Ambrym Island’s vast complex volcano system, featuring a large 12-kilometer-wide caldera that hosts two prominent active cones: Benbow and Marum. This complex volcano formed through repeated eruptions of basaltic lava flows and explosive activity that shaped the island’s rugged terrain. The volcano is renowned for its historically persistent lava lakes within the craters, a rare geological phenomenon. These lava lakes have been visible for decades, though recent eruptions have altered their activity. The volcano’s eruptions are typically strombolian to vulcanian in style, producing lava fountains, ash plumes, and lava flows confined mostly within the caldera. The caldera floor is covered with thick deposits of volcanic ash, scoria, and lava, interspersed with fumaroles emitting sulfur-rich gases and steam. This dynamic environment offers a unique window into volcanic processes and the ongoing evolution of a complex volcanic system.
