There are various factors that determine how far inland a tsunami can go. Here is a list of factors involved: The terrain of the land and the height of the tsunami wave. If the land is mountainous the tsunami would probably not go very far; however, if it is lowland, it may wash inland for several kilometers.Another important factor in a tsunami is the volume of water displaced. It is not the height of a tsunami that gives it momentum over land, but the length.The angle at which the tsunami reaches land and the geographical shape of the coastline: A concave coastline will suffer more damage than a convex coastline that can deflect the water movement.Land forms slow them down considerably. The distance travelled inland is directly related to the change in elevation.Note, an earthquake's imp
