Manam is a [[basalt]]ic-[[andesite|andesitic]] [[stratovolcano]], and despite remarkably symmetrical lower flanks has four distinct valleys, locally known as "avalanche valleys" due to their ability to focus avalanches and particularly [[pyroclastic flow]]s generated at the summit. These valleys represent the highest-risk areas during eruptions, and, when the island was inhabited, were typically the first areas to be evacuated during heightened activity. The earliest documented eruption of Manam was in 1616.<ref name=gvp/>
