February 27, 2010 Crescent City, California tsunami from M8.8 Chile earthquake

Filed in News 12 comments







Video of first 3 hours of tsunami inundation at small boat basin entrance of Crescent City harbor. Tsunami produced by M8.8 offshore Chile earthquake. The processed video is sped up by about 20X so that 3 hours is reproduced to be about 8.5 minutes in length. Note, the tsunami is not a wall of water but a series of long period waves, seen here as strong shifting currents in and out of the small boat basin. The surging and waning portions of the tsunami are about 15 minutes apart. This small boat basin typically has little or no current across the entrance. The anticipated maximum crest to trough amplitude of the tsunami was estimated by the West Coast Tsunami Warning Center to be about 0.6 m (2 ft). The change in sea level height is evident by the change in water height on the end of the rocky break-water directly across the channel. Several fishing and pleasure vessels moved out of the basin in advance of the tsunami. A few of them return during the course of the video and can be seen negotiating the channel in the swift currents of the tsunami.

    @RnBramwell you are so dumb

  • RnBramwell

    An excellent demonstration of the cyclic nature of a tsunami.

    Why do most films show just one or two giant waves, all in the space of 30 to 60 min? Of course, they inundate everything. Is it a function of distance from the epicenter, or bottom features along any given shoreline?

    I lost count of how many cycles are in the three hours of your video, The deepest ebb seemed to be around 5:30

    I can’t help but wonder about the apparent disconnect between public safety…and the SoCal media. NOAA in Oxnard issued the advisory…yet the major TV networks(except CNN)never got the word out. Same deal last Aug. 31-The Station fire blew up on a weekend…and local TV just wasn’t there(instead doing sports,cartoons,and infomercials).I’ve heard(first-hand)that Long Beach harbor didn’t inform the shift changes…which is amazing considering the shallow draft at that terminal. Incredible video.
