"A tsunami (pronounced tsoo-NAH-mee) or tidal wave is a series of waves (called a "wave train") generated in a body of water by a pulsating or abrupt disturbance that vertically displaces the water column. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis. Tsunamis can savagely attack coastlines, causing devastating property damage and loss of life."
A simulation on the BBC News site
" This simulation (2 MB) of the 1993 Hokkaido earthquake-generated tsunami, developed by Takeyuki Takahashi of the Disaster Control Research Center, Tohoku University, Japan, shows the initial water-surface profile over the source area and the subsequent wave propagation away from the source. Areas in blue represent a water surface that is lower than the mean water level, while areas in red represent an elevated water surface. The initial water-surface profile, as shown in this image, reflects a large, long uplifted area of the sea floor lying to the west (left) of Okushiri Island, with a much smaller subsided area immediately adjacent to the southwest corner of Okushiri."

Welcome! You are Dumptown's new City Manager! When you start to play, you'll see Dumptown at its worst — it's littered, polluted, and nothing is being recycled or reused. There are many trash cans and dumpsters, but no recycling bins. That means all of the trash is going right into the landfill just outside town, where it isn't doing anyone any good.In your new position, you can start programs that encourage Dumptown's citizens and businesses to recycle and reduce waste. You have 10 programs to work with. Each time you try out a new one, you can see immediately how the Dumptown landscape changes. You also see how much waste you are saving from going into the landfill Click here
