Probably occurring because of a large landslide on the south shore of the bay in the Mudslide Creek Valley, the wave had a maximum run-up height of 24 metres (80 ft), flooding the coast of the bay up to ...
“The most noteworthy of these tsunamis was in 1958, when a landslide entered the Lituya Bay Fiord in Glacier Bay and generated a wave that went 1,700 feet up the opposite side of the fiord ...
