Earthquakes are the main cause for a tsunami. This action causes the start of a tsunami and therefore leads to a heavy destruction. Earthquakes make a break in the earth’s surface. Whereas a tsunami just wipes out buildings and specific features of nature.
earthquakes are able to reach any area! It has no limits unlike tsunamis. It can destroy way more and even break earths crust, they can cause even avalanches! And damage roads making it hard for people to drive to where they need to go.
