They are large and sloping volcanoes that create a quiet eruption. … WebSubduction allows water from the subducting plate to be driven upward, off the subducting plate and into the mantle wedge. This lowers the melting point of the mantle, and it melts to form magma. This magma will rise and leak into the crust forming a volcano. This process can create a chain of volcanic islands. bluewater phone number grand cayman
