What was the magnitude of 1964 Oregon tsunami?

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.

What to do when a tsunami is heading towards the beach?

The safest thing to do when a large wave or tsunami is heading towards a beach is to run as far away as you can.Do not attempt to swim in the tsunami. If you cannot run, grab onto something solid like a lamp post or a large tree.If you think that there may be a tsunami brewing, do NOT GO TO THE BEACH, ever.
