7 Suppose there is a big earthquake in the middle of an ocean Suppose there is a big earthquake in the middle of an ocean. The ocean floor shakes and creates waves. These waves spread out from the center of the quake to all directions. They travel at a speed of miles per hour. As these waves come near the land, they start to slow down, but they begin to grow higher. Once these big waves break or hit the land, they can cause serious damage. People get killed. Villages get washed away. Buildings get ruined.
