This National Oceanic and Atmospheric Administration (NOAA) Global bathymetry map image released on March 11, 2011 shows features of the ocean floor depth (or bathymetry) from NOAA s ETOPO-1 dataset. The image shows the entire Western Pacific basin. Notice how abruptly the Japanese islands rise out of the ocean. Other coastal Asian areas have much more gradual slopes. The islands and mountain ranges throughout the ocean, visible in this imagery, also affect the tsunami travel time and speed. In the open ocean, tsunamis can travel at speeds up to 800 kph.

The vertical spray would be quite a sight after the wall of water hit that coastline, eh?
