The graphic displays qualitative and quantitative information about the tsunami including tsunami wave interaction with ocean floor bathymetric features, and neighboring coastlines. The tsunami radiation patterns are shown with color coded information about the maximum wave amplitude on top of the bathymetry map of the Pacific Ocean. Black contours show tsunami front travel time.
