Crescent City Harbor is one of the oldest on the Pacific Coast of 

 the United States. Over 100 commercial fishing vessels are based here, 

 as well as many pleasure craft and sport-fishing boats. Lumbering and 

 timber products are the principal industries of the city's population 

 of about 3,000. 



The first of the four damaging waves shown in the inferred marigram 

 of Figure k9e caused no damage other than inundation damage. The second 

 wave was smaller than the first. The third and largest wave was pre- 

 ceded by a considerable drawdown which left the inner harbor almost dry. 

 This wave then entered the harbor more as a fast-rising tide than a bore 

 (Magoon, I965). Evidence for this is found in the fact that the break- 

 waters suffered no damage (Tudor, 196U). Locations and characteristic 

 cross-sections of these breakwaters are shown in Figure 210a. The runup 

 line of this third wave is shown in Figure 209. Detail runup within the 

 city is shown in Figure 210b. 



In the harbor 15 fishing boats capsized and 3 disappeared. In the 

 fishing boat mooring area 8 were sunk. Several boats were washed onto 

 the beach at the beachfront development site, and the rest were beached 

 and capsized in scattered areas (Tudor, I96H ) . Figure 211 shows the 

 litter of flotsam at the northwest end of the harbor the next day. 

 Downcoast, the scatter of wreckage shown in Figure 212 is typical of 

 hundreds of miles of the coastline northward in Oregon and Washington 

 as it looked after the giant waves . 



In the harbor, Citizens Dock suffered severely. It was constructed 

 in 19^9, and since then, additional construction and repair had expanded 

 and kept the dock in good shape. Figure 213 shows a typical section of 

 the dock. The largest wave caused a moored lumber barge of immense 

 inertia to smash into the dock (Figures 2lU to 217). Adjacent to the 

 area where the barge was moored, the dock planking of the cargo pier 

 was pushed into piles resembling giant jackstraws. The corbels, decking, 

 fender systems , and bollards were so badly damaged that they all needed 

 to be replaced (Tudor, 196U). 



The dock area, forward of the moored barge location, received 

 damage to its blocking compound, ribbon fenders, and wheel guards, all 

 of which required rebuilding. The area to the stern of the barge was 

 slightly damaged and required some rebuilding. 



The only damage to the fish pier on Citizens Dock (Figure 2lU) was 

 along the centerline. Here the deck was raised about 6 inches .because 

 of a lack of steel straps between pile caps and stringers. The commer- 

 cial fish shacks on the pier were displaced as shown in Figure 2l8 

 (Tudor, I96U). 



The approach to Citizens Dock was also damaged and badly twisted 

 when, under the force of the tsunami, the deck was buoyed and the
