MetadataShow full item record
The Puget Sound region with its high, steep bluffs is subject to landslides. An area of Puget Sound off Camano Island, near Onamac Point, was studied to determine if sediments there were a result of a landslide. The volume of material was estimated and dated to have been deposited as a result of a large earthquake 1,000 years ago. The landslide may have caused a tsunami in Puget Sound that reached Whidbey Island.
