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.
