Depends on the size of the earthquake that causes it.
ADDED: Also of course, the topography and altitude of the coast; and the nature of any barrier such as mangrove swamps, which are effective breakwaters.
Tidal waves can stretch up-to a very long distance, it can go onto the land at the speed of 100 metres atleast, they are very dangerous and occur at Coastal areas.
it depends how big.
the top of a hill or a PLASE far away from the sea
300 Miles inland! get used to it man!
The tsunami can flood as fast as a commercial jet plane.
The extent to which a 5000 foot high wave would go inland depends on various factors such as the slope of the land, obstacles in its path, and the initial strength of the wave. Generally speaking, a wave of this magnitude could potentially cause significant damage and travel several miles inland in flatter coastal areas, while in steeper terrain or areas with natural barriers, its inland penetration would be more limited.
I read the one in Indonesia got up to 30 meters high and went as far as 3km inland. this means for every 10 meters in height the wave can travel 1km inland.Using the above formula, a 2km high wave (2000 meters), could travel 200km inland (2000/10=200).This may be incorrect tho as the waves energy may grow exponentially with height. If this is true it could travel a LOT further inland.Obviously terrain height and natural geographical resistances such as, hills, valleys, forests etc. will use up more of the waves energy and shorten the distance it can travel.In Conclusion:If you were 300km inland and there was a mountain range in between you and the ocean you should be 99.99% safe :)Keep in mind you also need to make sure your not near a fault line or extinct volcano if 2012 becomes real.

It would depending on the height of the terrain and sea level. However, if it was a flat piece of land, it would easily crest a couple hundred miles inland.
A tidal wave is what tsunamis used to be called. The Japanese name has been adopted more recently because of the mistaken impression on the part of the public that a tidal wave was an extremely high tide (see also Neap Tide). A tsunami, unlike a regular wave, does not come in and go back out. The waves have no chance to go out and consequently pile up on top of each other driving far inland.
Land forms slow them down considerably. The distance travelled inland is directly related to the change in elevation. It would be interesting to see how far inland this March 11th, 2011 tsunmai travelled past Antioch, California up the delta area.
