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.

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.

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.

Emily Reynolds, a graduate student, looks through a spotting scope. The student is watching sea otters in Kachemak Bay forage. USGS researchers spend hundreds of hours annually observing sea otter foraging behavior to document prey composition and energy recovery rates.
