When oceanic and continental plates collide the denser oceanic plate subducts the continental plate and enters the mantle where it melts. Magma can rise through the lithosphere and erupt as lava through volcanoes. As the oceanic plate subducts, it gets stuck due to friction. Pressure builds up until it is released as an earthquake.
