    Should I assume this is another Fox lie?

    Not really. We have a tsunami warning system here in Oregon, but in a recent test, some small town mayors opted out of the test.

    This kind of event would collapse bridges and overpasses from Cape Mendocino in California, to the north end of Vancouver Island. Even though we have strong earthquake codes, they are not designed for magnitude 9 quakes. In fact, until Dr. Brian Atwater did his paleo-seismic studies, no one realized that we had that magnitude of quakes here.

    Also, there are is geography here that could increase the damage. The Puget Sound may sietch, causing a runup higher than anticipated. In the Staight of Juan de Fuca, they have found driftwood from that quake and tsunami as high as 500 ft.

    The isolation from the downing of the roads and railroad bridges could increase the death toll and misery should the quake happen during the winter as it did on 26Jan1700. There are many areas in population centers that are prone to slides just from excessive rain periods. Were the quake to occur during one of these periods, it would substancially increase the toll.

    So, what should someone living here do about this? Plan for a basic two to three week period with no tap water, no access to food or fuel. In a house that may be no longer structurally sound, and lack windows, if it is still standing.

    Will it happen in the next fifty years? Possibly. Or it could happen tomorrow, or not in the next century. We know too little about the periodicity of these quakes to be able to make a good guess in this area.

    They had a set of articles on the issue in today's paper. Several coastal towns got badly damaged from the Japan Tsunami last year. Most of the focus was between Depot Bay in about the northern third of the Oregon Coast down to Crescent City CA.

    from the Oregonian link above

    Like Rocky pointed out, part of the damage was because of the shape of the bay. Instead of reducing the damage, it can intensify it.

    In theory, this area is very active. I live on the side of a volcano here inside the city limits of Portland. In practice things are the level of quiet one associates with something really big and nasty getting ready to knock our socks off. Maybe not today, maybe not tomorrow, but on some day sooner than we are ready for we are in for a serious shock

    And you know that famous wave picture from Japan.... That is what the picture is about. The earthquake between British Columbia and Washington that sent a 30 foot wall of water all the way to Japan.
