hi richard!!! your question is bit tricky. Ocean rise and earthquake and volcanic eruptions are two different things. Basics: Ocean rise is the rise in the water level and earthquakes and volcanic eruptions are due to plate tectonics. We see a rise in ocean level due to the effect of global warming, i.e rise in atmospheric temperature which results in the melting of ice in the poles and increases the volume of water. We experience earthquakes and volcanic eruptions due to movement in certain region of the Earth's crust, called plates. This is due to the pressure buildup in magma which erupts from a volcano and also sometimes when this pressure is experienced below a plane surface there is a movement in plates and smokes and fumes are emitted out. you can find more information in books on Marine Geology or any Basic Marine Science books like Truman and Webber.
