Slumping along the Alaska Railroad right-of-way evolved into long-runout landslides. The same area failed in earthquakes in 1954 and 1964.

Eklutna Lake dam appeared to be undamaged the day after the earthquake; overflights of the lake showed no landslides impacted the lake shoreline.

USGS scientists conduct an aerial inspection of a line of sand vents along the Cook Inlet tide flat at Earthquake Park in Anchorage. Cook Inlet coastal plain liquefaction and bluff raveling near Earthquake Park. These vents opened and ejected sand due to liquefaction triggered by strong shaking during the M7.1 November 30, 2018 Anchorage earthquake.

Minnesota Blvd off-ramp failure under repair. Construction crews rebuild the Minnesota Drive onramp in Anchorage on December 1, 2018. Engineered fill beneath the onramp failed the day before as a result of strong shaking during the M7.1 November 30, 2018 Anchorage earthquake.

USGS scientist, Chris McNeil, measures and weighs an ice core extracted from Wolverine Glacier to determine the density of the firn layer.

A scientist prepares to extract a snow core from one of the Benchmark Glaciers. Cores are used to determine the density of the snow and ice on the surface of the glacier in order to determine the mass balance.

Group of walruses hauled out on beach near rocks at bottom on cliff. The photo was taken at Cape Seniavin on the Alaska Peninsula. 

Aerial view of the edge of a large walrus herd hauled out on the northwestern shores of Alaska.  The image was taken using an unoccupied aerial system, commonly referred to as a survey drone that was flown to collect imagery of walruses resting on shore in 2018 and 2019 for estimating the abundance of walruses that use the U.S.

Walruses identified as being in an appropriate position for measurement from an image collected by a USGS survey drone on September 6, 2018, at a haulout near Point Lay, Alaska.
