Detailed Description
Wave heights are highly exaggerated in these screen shots from computer animations of the tsunami generated by the March 11, 2011, magnitude 9.0 earthquake. View northward in top image, southward in bottom image. View the animations, created by USGS research geophysicist Eric Geist. A wave trough was the first part of the tsunami to reach the shore. Note the drawdown as water flows away from the shore while the first crest approaches. Vertical exaggeration is approximately 10:1 for features on the land (green) and sea-floor (blue); wave heights are greatly exaggerated with respect to topography for visualization purposes.
