Alaska Earthquake March 27, 1964. The rails in this approach to a railroad bridge near the head of Turnagain Arm were torn from their ties and buckled laterally by streamward movement of the riverbanks during the earthquake. The bridge was also compressed and developed a hump from vertical buckling. Figure 24, U.S. Geological Survey Professional paper 541.
