Today in Earthquake History July 10th

A massive rockslide at the head of Lituya Bay caused water to surge about 530 meters, generating a "gravity wave" that swept out of the bay. A fishing boat anchored in Anchorage Cove was carried in front of the largest wave crest, and those onboard estimated they cleared La Chaussee Spit (at the mouth of Lituya Bay) by 30 meters or more. Two people on another fishing boat disappeared after being caught in the huge wave. The water, estimated to have traveled about 100 miles per hour, swept away a lighthouse and a log cabin - the only manmade objects in the area
