Atwater has spent much of his career studying the likelihood of large earthquakes and tsunamis in the Pacific Northwest region of North America. In 2005, he published a book with others, "The Orphan Tsunami of 1700," that summarizes the evidence for an 8.7–9.2 M w megathrust earthquake in the Pacific Northwest on 26 January 1700, known as the 1700 Cascadia earthquake.
Lituya Bay is a fjord located on the Fairweather Fault in the northeastern part of the Gulf of Alaska. It is a T-shaped bay with a width of 2 miles (3 km) and a length of 7 miles (11 km). [8] Lituya Bay is an ice-scoured tidal inlet with a maximum depth of 722 feet (220 m). The narrow entrance of the bay has a depth of only 33 feet (10 m). [8]
The 2001 Nisqually earthquake occurred at 10:54:32 local time on February 28, 2001, and lasted nearly a minute. [5] The intraslab earthquake had a moment magnitude of 6.8 and a maximum Mercalli intensity of VIII (Severe). The epicenter was in the southern Puget Sound, northeast of Olympia, but the shock was felt in Oregon, British Columbia ...
Tsunami preparedness in Washington has grown in recent years, and for good reason. Washington state has more than 3,000 miles of coastline that is home to 58 coastal communities and sees millions ...
The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700, with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca Plate from mid- Vancouver Island, south along the Pacific Northwest coast as far as northern California. The plate slipped an average of 20 meters (66 ...

National Tsunami Warning Center. The National Tsunami Warning Center (NTWC) is one of two tsunami warning centers in the United States, covering all coastal regions of the United States and Canada, except Hawaii, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands.

Channeled Scablands. The Channeled Scablands are a relatively barren and soil-free region of interconnected relict and dry flood channels, coulees and cataracts eroded into Palouse loess and the typically flat-lying basalt flows that remain after cataclysmic floods within the southeastern part of Washington state. [1][2] The Channeled Scablands ...
