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.

Annotated photo of ake00346. Album caption: A subsidence trough (or graben) formed at the head of the "L" Street landslide in Anchorage during the earthquake. The slide block, which is the virtually unbroken ground tot he left of 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.

Compare the damage sustained by the Hillside Apartment Building and the adjacent three-story wood-frame dwelling with the tall chimney. In general, wood frame buildings in Anchorage sustained little damage from seismic vibration.

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 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.

This map shows the extent of ground disrupted by the Fourth Avenue Slide and some of the measured displacements. Much of this area north of Third Avenue has since been re-graded and reinforced. The North-facing slope dropping into Ship Creek has been reinforced at its toe with a buried gravel buttress, giving the park its name.

Arc-shaped bluff that many interpret to be evidence of landsliding during a pre-1964 earthquake of unknown age. The Frank and Maxine Reed Family Staircase at this stop was built to accommodate pedestrian traffic over a steep bluff along West Twelfth Avenue which is made discontinuous by the bluff. There was no sliding on this feature in 1964.

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.

A raft of sea otters near Cohen Island in Kachemak Bay, Alaska. Sea otters rest together in groups called rafts. A raft can generally contain 10 to 100 sea otters. You will see either all male or all female with pups rafts.
