How was kilauea formed

May Less dense than the solid rock of the plate, the magma rises through the mantle and the crust as a thin thermal plume, erupting beneath the ocean to form an active seamount. As the plate moves away, the volcano stops erupting and a new one is formed in its place. Over time, the countless eruptions increase the height of the seamount until it breaks the ocean surface and becomes an island volcano. This is where magma upwells and creates a volcano.
