The magnitude of the quake was about 8.3, although some sources say it was a 7.9, on the Richter scale. The temblor "shook" loose an estimated 40 million cubic yards of dirt and glacier from a mountainside at the head of the Bay. " When the debris went "kersploosh" into the water it created a massive wave that washed 500m high over the headland in the left side of the above picture. The tsunami inundated approximately 5 square miles of land along the shores of Lituya Bay, sending water as far as 3,600 feet inland, and clearing millions of trees.
