Matt Haughey on the tsunami:

So live news coverage in America is basically staring at webcams and reading wikipedia? Shit, I could be doing this myself.

    I was already completely steamed about media hysteria over “snow hurricane,” in which Greenwich had maximum winds of 26 mph at the official station at HPN airport. Then, first thing Sat. am we get this official tsunami warning, advising world governments that a 2 to 3 ft tide like long-wave is going their way.

    And how does the media react? With “flee to the mountains” hysteria. Panic – a 400 mile per wave will inundate all beaches. A graphic on CNN showed 15 story hotels with waves breaking over them.

    Here was the actual warning text with a follow-up explanation of the actual amplitude (0.9 ft in Inquique, Chile in first line, etc):

    When an earthquake of subduction type occurs, the sea-floor drops. In this case about 400 miles by several miles wide a drop of 20 to 30 ft, but at a depth of 22 miles.

    This drop sucks in seawater, which generates a wave with the negative portion in front. That is, a low tide ripples moves outward, followed by the backwash high tide.

    When my daughter lived in the Peruvian fishing village, the natives warned her that a sudden low tide was the warning sign to flee for higher ground.

    What really bugged me in the coverage is that while the commentators were watched this occur in Hawaii, they seemed completely ignorant, despite their many experts, that they were actually watching the tsunami in progress.

    They were all expecting giant breaking waves, rather than the widely advised and warned fluctuation between minus 2 – 3 ft sudden low tide, followed by the 2-3 ft rapid high tide.
