First you need to find out if the place you are visiting has a high risk of tsunamis, if it does you should prepare. To prepare for a tsunami one good idea is to have a safe evacuation route preferably to a high mountain were the water can not reach you. Also, you should listen to radio warnings about tsunamis and follow instructions. Scientists are also working on technology to fight tsunamis and improve technology for detecting tsunamis. You can help by raising money for this research. For more information about tsunami preparation click the link down below.
History Of Tsunamis
One of the earliest tsunamis ever recorded happened when a Persian army attacked Greece. During the attack all of the water in the ocean disappeared so the army crossed but then all the water came back as a giant wave and killed the Persian army. The Greeks thought this was an act of their god Poseidon but it was really a tsunami.
A very famous tsunami which occurred during the 1755 Lisbon earthquake almost destroyed Portugal. It occurred on Saturday, 1 November, the holy day of All Saints' Day. In combination with subsequent fires and a tsunami, the earthquake almost totally destroyed Lisbon the capital of Portugal. Seismologists today estimate the Lisbon earthquake had a magnitude in the range 8.5–9.0. The death toll is not quite known but it is thought to be about 100000. This tsunami began the science of seismology.
