Tsunami!
a short video about tsunamis www.youtube.com The 2004 Indian Ocean earthquake was an undersea earthquake that occurred at 00:58:53 UTC on December 26, 2004, with an epicentre off the west coast of Sumat...
When the wave comes to shallow water, the energy is compressed, causing the wave to rise up, but only the largest waves 'crest' and break. Most often, a large surge of water rolls in 3-5 meters high, but 30 meters high is not unheard of. cache2.asset-cache.net
If the trough of the wave comes in first, the sea will seem to pull out like a super-low tide. If you see this, RUN! www.ermlegalsolutions.com

water is put in motion by movement due to 1) plate upthrust, 2)slumping (normal fault), 3) landslide or 4) meteorite impact <br /> docs.google.com A reverse fault upthrust (at a convergent boundary) moves water upwards. This is the most common type due to subduction along the Ring of Fire. A normal fault (slumping) moves water downward initially, but this will ‘rebound’ upwards. An underwater landslide will cause some move...
Water moves outward from focus; energy is spread from top-to-bottom of water column, not just at the surface! www.uihome.uidaho.edu
Wave height is small in the open ocean (several feet high), but wavelength can be 120 km (crest-to-crest), traveling at 800 kph (500 mph)! site-closed.wikispaces.com
Highest wave recorded was over 500 m tall ion Lituya bay, Alaska, caused by a landslide. www.youtube.com YouTube
