Why does every tsunami travel differently?

Question

Tsunamis are quite interesting, as they only happen after a large displacement of water. Usually, the waves travel quite weirdly. Sometimes there are waves which bounce off of land and go back to sea. Sometimes they go straight to land and don't bother any other pieces of land around them. So why does this happen? Why do some tsunamis go straight to land while others are spread out? And why others take various pathways toward land or the open sea?

Answer 1

Wave motion in water depends on many factors, including the shape of the container, the texture (which affects friction), wind speed, gravity from the moon---and more. Any analysis or prediction would be pretty difficult. Some Google searches will surely find something....
