Tsunami Details

Here at OEM we are monitoring the tsunami. For Oregon it is predicted to be negligible (around half a meter or about 1.5 - 2 feet), but local sea floor and terrain in some areas might make the wave a little larger. Tsunami wave heights peak about 2 hours after they arrive. So we recommend that you stay away from the beach until after the event.

The estimated times of arrival for Oregon are found at http://wcatwc.arh.noaa.gov/2010/02/27/725245/09/webeta725245-09.txt

FEMA has a youtube channel, not sure if you knew that or not.
