The volcanoes form on the continental side of a subduction zone. The melting oceanic crust forms pools of molten rock in a magma chamber. The magma, molten rock, in the magma chamber is lighter than the volcano rocks that surround it.The magma works its way to the summit where it erupts as tephra or in thick lava flows. Lava eruptions on stratovolcanoes.he melting oceanic crust forms pools of molten rock in a magma chamber.
