This map above shows the propagation of the Tsunami that was generated earlier from an 8.0 earthquake that occurred over American Samoa in the early afternoon hours (Iowa Time) Tuesday. The largest waves (over 5 feet) stayed within 500-1000 miles of the earthquake, with smaller waves (roughly 1-2 feet) reaching the western coasts of North and South America a few hours ago.
