Eyewitnesses have reported that the second damaging wave which 

 struck at 7:^0 p.m. (Figure 38a and Appendix A) was a breaking wave along 

 the southwest shoreline of Womens Bay (Kachadoorian and Plafker, 196T). 

 This is not surprising in view of the extremely flat slope of the tidal 

 flats in this region (Figure 88) and the fact that the withdrawal of the 

 previous wave would have exposed the seabed near the hairpin bend of the 

 bay. Additional information on this wave comes from Mr. and Mrs. Louis 

 Schultz (Kachadoorian and Plafker, I967), who were on the Chiniak Road 

 Figure 88), presumably near Womens Bay, when the wave struck. It rolled 

 in rapidly as a wall of water about 3 feet high and was followed immedi- 

 ately by a series of surges. Each surge raised the water level by jumps. 

 This is typical of a bore or large wave running up a flat beach gradient . 

 The darkness of the night precluded further observation of later waves, 

 and no reports are available other than the measurements logged at the 

 Fleet Weather Central (Appendix A). 



The total damage to buildings, materials and equipment at the Naval 

 Station, resulting from the earthquake, was said to be in excess of 

 $10,000,000 (Tudor, 196^). Most of this damage can be attributed to 

 the tsunami. A listing of damaged structures and estimates for their 

 restoration or replacement is found in Table E-3 (Appendix E). 



The Cargo Dock on the north shore of Womens Bay (Figure 113), already 

 deteriorated, was completely destroyed (Figure 115). According to Tudor 

 (196U), the tsunami violently moved a moored ship which lifted the bol- 

 lards and damaged some fendering. The elevated water buoyed sections of 

 the pier decking off the pilings and moved them laterally, thus causing 

 failure of many framing and bracing members. Several piles were pulled 

 from their pile holes intact along with the elevated decking. The reason 

 for this is that great trouble had been experienced originally in driving 

 the piles into the rocky bottom on the northside of Womens Bay, and in 

 some instances pile holes had to be augered. When the flood water re- 

 ceded, the buoyed decking and extracted piles crumpled the dock as shown 

 in Figure 115. 



The Marginal Pier and the Tanker and Fender Pier (fuel pier. Figure 

 113), suffered only minor damage. At the Marginal Pier, a moored barge, 

 under tsunami action, loosened a bollard and some of the decking (Tudor, 

 196k). The pier had to be loaded down with anchor chains after the 

 earthquake to prevent flotation on the high tides which, after the 

 earthquake, reached to higher levels than previously owing to a 5.6-foot 

 subsidence of the land (Figure II6). Because of this complete rebuilding 

 of the Marginal Pier had to be undertaken later. 



Two small, waterfront structures, the Hobby Shop Boat Repair House 

 and the Engine Generator Building (Figure 113), were completely swept 

 from their foundation pilings. Figure 117 shows the Boat Repair House 

 after the earthquake right alongside of its own pilings. The Hobby 

 Shop itself was moved and broken in two pieces (Figure II8). The Ground 

 Electronics building was damaged as shown in Figure 119. Here a side 

 wall apparently failed under hydrostatic pressure of water at a level
