An Oct. 26, 2012 photo shows a large driling rig, at right, waiting for a custom drill bit to install bigger and stronger dock pilings to take the place of docks destroyed by the 2011 tsunami from Japan. Once it overcomes some construction delays, the port hopes to have the West Coast's first harbor designed to withstand the kind of tsunami expected to hit every 50 years. Due to the formation of the sea floor and the configuration of the harbor, Crescent City regularly takes the biggest hit of any port on the West Coast from tsunamis, whether they come from Chile, Alaska or Japan.
