TOKYO - Japan's Meteorological Agency issued tsunami warnings Saturday following a magnitude 8.3 earthquake in the Pacific Ocean.

The agency says a 3.3-foot-high tsunami could hit the northeastern coast of Japan's northern island of Hokkaido around 2 p.m. (12 a.m. EST).

Anyone know how much damage a 3.3 foot high tsunami could cause?

The really bad one's are caused by landslides, not earthquakes. 3.3 ft is tiny.

Wasn't the December 26th tsunami caused by an earthquake?

And if I remember correctly the waves were not very high there either.

Oh, well damn. I watched like 5 hours of tsunami shows one day and they were all about the landslide ones. Anyway, 3.3 ft seems really small, doesn't it? They were talking about the landslide ones being 100+ ft. I guess 3.3 still might be enough to do a lot of damage though. Guess I was a little confused.

Sounds like some Discovery Channel nonsense. 3.3 feet could be huge. The last one wasn't very high, it's the speed & amount of water that do the damage. Scientists measure the energy of the wave, which is the amount of mass and how fast it's moving. Also, breaking waves are more about the sea floor, not the amount of energy, yes a high front and crash looks impressive but that actually dissapates energy and prevents it from travelling inland, a steady swell is more dangerous.

3.3ft seems small, but is a massive volume of water, I imagine it won't go very far inland but should cause a lot of damage where it hits
