For many, earthquakes and tsunamis are terrifying yet distant concepts from news reports. Understanding them requires connecting abstract terms like "plate tectonics," "faults," "energy release," and "water wave propagation" into a dynamic story with cause and effect, a timeline, and a sense of space. The power of interactive simulation technology lies in its ability to allow people to become active initiators and observers of this "story." By controlling a simple physical interface (such as a joystick) to simulate the effects of geological forces and instantly seeing their scientifically validated virtual consequences (such as earthquake animations and tsunami simulations), a profound and solid understanding of cause and effect can be built—something that passive viewing cannot achieve. Standing before our "Undersea Earthquake" exhibit, you are faced with a miniature geodynamics laboratory. At the heart of the exhibit is a physically movable "plate tectonics" sand table and three joy
