Mega Tsunami Vids

To get a brief lesson on mega Tsunamis, watch this video.
if you got about 45 mins. to kill, watch these in parts. Part One:awww, man, the other parts won't upload. If you really want to see them, got to Youtube and type, "Mega Tsunami: A Wave of Destruction" And if your lucky enough to see it, theres a documentary on it on Discovery Channel.

How they are caused

Now, most normal tsunamis only rise about ten meters, and are caused by earthquakes. A Mega-Tsunami can rise up to hundreds of meters and are caused by massive land slides. (see post # 2)
