It is advisable to list some safety measures during an earthquake or tsunami. Then this answer will only be helpful to you. Tsunami is a giant sea wave which is caused mainly due to earthquakes occurring undersea. When an earthquake or a volcanic activity takes place, a large amount of water may get displaced. The displaced water forms waves. These waves when approach the shallow water in the coastal areas, becomes high and crashes onto the shore. Tsunami causes widespread destruction of lives and property.
