Tsunamis
Earthquakes, believe it or not, can be even more destructive than they already are. When an earthquake appears out at sea the force of the tectonic waves is so powerful it will create a gigantic wave in the water. Not one of those waves that a surfer rides on, this wave is one that floods entire towns and causes many deaths. Tsunamis move towards the shore and slow down as they hit the shore causing water to flood a city and drag many people out to sea.
