Ground motion is when the shaking of the ground causes the passage of seismic waves, especially surface waves, near the epicenter of the earthquake. Ground motion is responsible for the most damage during an earthquake and is thus a primary effect of an earthquake. Aftershocks are smaller earthquakes that occur after a main earthquake, and in most causes there are many of these. Fire is a hazard of earthquakes, because power lines may be knocked down and natural gas lines may rupture due to an earthquake. Fires are often started closely following an earthquake. Tsunami is another hazard of earthquakes. They are giant ocean waves that can rapidly travel across oceans. Earthquakes that occur beneath sea level and along coastal areas can generate tsunami, which can cause thousands of miles away on the other side of the world. Flooding is a hazard that may occur due to rupture of human made dams and levees, due to tsunami, and as a result of ground subsidence after an
