This truck at Lowell Point, 2 miles from Seward, was bent around a tree by the surge-waves generated by the underwater landslides along the Seward waterfront. The truck was about 32 feet above water level at the time of the earthquake. Many landslides generated by the 1964 earthquake originated beneath, or came to rest within, large bodies of water.

An underwater landslide in Blackstone Bay produced a large wave which surged to points 80 feet above sea level. The trees in the photo are about 50  to 75 feet high.

The modern wave-cut bedrock surface surrounding Middleton Island (the flat surface between the base of the cliffs and the water) was submerged at a comparable stage of tide before the earthquake.

The Turnagain Heights landslide in Anchorage occurred along a steep bluff fronting Knik Arm of Cook Inlet. Its length, which was parallel to the bluff, was about one and half miles; its width was about a quarter to half a mile. This landslide reduced to rubble many of the finer homes of the city of Anchorage.

Anchorage municipal wharf area shortly after the earthquake at low tide. The main dock was only slightly damaged, but the older Army dock (upper left) was ruined. Vibration and ground fractures damaged some structures in the port area, including the petroleum tank (lower right). Photo by U.S. Army.

The 1200 "L" Street Building in Anchorage, a fourteen-story reinforced concrete apartment building, was severely damaged during the earthquake. One the main exterior piers (the white bearing walls without windows)shown in this slide, failed at the second floor, exposing the steel reinforced bars within the concrete.

The marquee of the Denali Theater, which was in the graben of the Fourth Avenue landslide in Anchorage, subsided until it came to rest on the sidewalk in front of the theater, which was on ground not involved in the landslide.

Alaska Earthquake March 27, 1964.

A subsidence trough (or graben) formed at the head of the L Street landslide in Anchorage during the earthquake. The slide block, which is virtually unbroken ground to the left of the graben, moved to the left. The subsidence trough sank 7 to 10 feet in response to 11 feet of horizontal movement of the slide block.

Damage to building from seismic vibration. The Fifth Avenue Chrysler Center in Anchorage was constructed of pre-cast, pre-stressed concrete roof T's which rested on concrete block walls in most parts of the building. However, in the showroom area the roof T's rested on reinforced concrete columns.

Damage to building from seismic vibrations. The Alaska Sales and Service building in Anchorage, which was under construction, partially collapsed during the earthquake. The building was constructed of pre-cast and pre-stressed concrete roof "T"s which rested on pre-cast reinforced-concrete T-columns, and it had pre-cast reinforced-concrete walls.

The Four Seasons Apartments in Anchorage was a six-story lift-slab reinforced concrete building which crashed to the ground during the earthquake. The building was under construction, but structurally completed, at the time of the earthquake.

The control tower at Anchorage International Airport fell to the ground during the earthquake. It was a split-level structure that was seven stories high on one side and built of reinforced concrete.
