Travel times for Tsunami conditions
« on: February 27, 2010, 08:12:33 AM »
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.

Interesting how it slows along the coast. the estimate time for San Fransisco is 27 min after Point Reyes which is far north of SF.

has to turn and travel east it also slows.  There are several places it list that travel time  is later then the open water times.

By the way been thru couple waves at sea. What was interesting was the water color changed in blueness. Also could feel the ship shudder from the engry in water as it passed. Was no heigth to it
