Unlike earthquakes, tsunamis are not classified by "magnitude". Rather, they are usually classified by "run-up", which is the same as 'flood elevation". Run-up can be measured on ocean beaches or in estuaries and river systems. The amount of damage caused by a tsunami depends on flood height, but also on how low the adjacent land is and the amount of development near the shoreline.
The highest tsunami run-up on the Oregon Coast from the March 24, 1964, Good Friday Earthquake was 18.5 ft above prevailing tide on the open beach at the City of Seaside. Within the estuary and rivers of Seaside, run-up averaged 8.5 ft above tide. This is the highest run-up known for that tsunami in Oregon. Only Crescent City, CA, on the west coast of the contiguous USA, had higher wave run-up and considerably more damage than Seaside.

Where did a recent tsunami that happen in the US?
Perhaps the most famous, and possibly the last major tsunami in the USA was from the 1964 Alaska earthquake with a resulting tsunami hitting Alaska, and traveling as far a Hawaii and the Oregon/Washington coast.http://en.wikipedia.org/wiki/1964_Alaska_earthquakehttp://ezinearticles.com/?Alaska-Earthquake-and-Tsunami,-1964&id=9558Another Tsunami was the Lituya Bay, Alaska Tsunami in 1958.http://geology.com/records/biggest-tsunami.shtmlSince the Alaska Earthquake in 1964 and the resulting Tsunami, the West Coast of the USA has had a Tsunami early warning system with emergency evacuation plans. There have been a couple of alarms from earthquakes, but no significant waves.Unfortunately, due to human nature, many people flocked to the coast after recent tsunami warnings.
Does Oregon have tsunamis?
There are several scenarios which can cause a tsunami to hit the Oregon coast. A large earthquake anywhere in the Pacific, volcanic eruptions, and large landslides are probably the three most likely.
