Shield Stages
The shield stage of the volcano is subdivided into three phases: the submarine, explosive, and sub aerial. During this stage of growth, the volcano accumulates about 95 percent of its mass and it takes on the "shield" shape that shield volcanoes are named for. It is also the stage where the volcano's eruptive frequency reaches its peak.
