        1. a volcano is another cause when a volcano erupts underwater due to the immense force coming from under the water the result is the displacement of water
        2. main occurrence area
          1. the main occurence area for tsunamis is the ring of fire also know as the pacific belt.

                    2. what is a tsunami?

                        1. structures
                          1. structures using heavy and string materials like heavy steel can withstand tsunamis better.
                          2. early warning systems (EWS)
                            1. a early warning system uses technology that predicts tsunamis and when one happens sends out alearts to citizens to warn about one.
