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.
