NOAA has released this map showing the tsunami wave heights across the Pacific Ocean today in the wake of the M8.9 earthquake in Japan: As you can see the highest waves are predicted south and east of Hawaii, extending all the way to the coast of Chile. The waves that hit Hawaii a couple of hours ago only reached 3-4 feet, and apparently have caused no serious damage. Compare that to the reported 33-foot height of the main tsunami that struck Japan.
