Japan Tsunami Earthquake Information & Estimated Times of Initial Tsunami arrival

The following list gives estimated times of arrival for locations along the North American Pacific coast from a tsunami generated at the given source location.  The list is ordered by arrival time starting with the earliest. Since tsunami speed is directly related to water depth, tsunami ETAs can be computed independent of tsunami amplitude.  THE LISTING OF A TSUNAMI ARRIVAL TIME BELOW DOES NOT INDICATE A WAVE IS IMMINENT. The listed arrival time is the initial wave arrival.  Tsunamis can be dangerous for many hours after arrival, and the initial wave is not necessarily the largest.
