Instructions: Click somewhere on the left side of the applet to get a wave pulse started running to the right.
The point where you click above the sea level decides how high the initial pulse is. After that, watch how
the tsunami hits the coast. You can pause the simulation by hitting the "s" key. Hitting 1, 2, or 3 changes
the shape of the sea bootom near the coast. Anytime you click on the applet it is restarted.
