Using CHDK on my bottom of the line Canon PowerShot I shot about 60 photos on a time lapse setting (one every 30 seconds) of Port Angeles Harbor between about 2:30 and 3:00 PM local time. I got lucky - the periods of the tsunami waves propagating through the Strait of Juan de Fuca are about 30 minutes - so I captured a full wave before my POS camera failed. The currents generated within the harbor associated with these waves are fairly minimal, though there is a noticeable current at the entrance - maybe 2-3 knots. NOAA CO-OPS data suggests a wave amplitude at this time of about 50-60 cm. You sort of have to look close - focus first on the dock piling in the near field.
