There is a silence... followed by dark walls blocking the sun. Suddenly there is a sound like a lion learning to roar. The sound grows louder as the walls grow taller. Nobody sees the wave until it's too late. People, ships never found for years if at all. A painless death slowly engulfs the lungs...
