Tsunami,Killer Wave!
Tsunami in USA

As we already know most tsunami occur in the Pacific Ocean because of the “ring of fire”, a zone of very active features in the earth’s crust. This is the most geologically active region on earth because of the frequent earthquakes and volcanic eruptions.
The Pacific Northwest: from Oregon to Alaska, is located at the edge of the North American plate along the “ring of fire”.
In the area of western British Columbia, Washington and Oregon three junctions are formed: the Juan de Fuca plate, the North America plate and the Pacific plate. The Explorer plate and Juan de Fuca plate are separated by the Nootka fault. (See
tectonic plates picture)
