The front of Lituya Glacier with lateral and medial moraines is seen terminating in Gilbert Inlet. On July 9, 1958, an earthquake caused a landslide in the Gilbert Inlet at the head of the bay, generating a massive megatsunami which had sufficient energy to run up the hill slope just opposite of the landslide to a height measuring 1,722 feet (525 m), taller than the Empire State Building and snap off all the trees. The giant wave runup of 1,720 feet (524 m.) at the head of the Bay and the subsequent huge wave along the main body of Lituya Bay which occurred on July 9, 1958, were caused primarily by an enormous subaerial rockfall into Gilbert Inlet at the head of Lituya Bay, triggered by dynamic earthquake ground motions along the Fairweather Fault.
