What is the name of tectonic plate off the coast of Washington and Oregon?
This is known as the Juan de Fuca Plate. Please see the related links.
Is the east coast of North America an active plate boundary?
No, the east coast of the United States is in the middle of the of the North American plate. The eastern most part of the North American plate boundary is in the middle of the Atlantic Ocean in an area known as the Mid-Atlantic Rift. The north western coast of North America (Oregon, Washington, Canada and Southern Alaska) are subduction zones.
Where is subduction most likely to occur?
Where an oceanic plate dives under a continental plate (e.g. just offshore the Washington/Oregon coast, creating a line of explosive volcanos just inland).
What plates are being subducted under Oregon and Washington?
Juan De Fuca Plate
What are the names od the plates that are involved in the collision of the coast of Washington?
Along the entire west cost is the Pacific Plate (Ocean) and the North American Plate (Land) however along Washington and Southwestern Canada is the Juan De Fuca Plate. So a collision on the coast of Washington would be between the Juan De Fuca Plate and North American Plate
Why are volcanoes on the west coast?
It is probably because the East Coast is not beside faults or at the edge of and tectonic plates. If you look at the West Coast, California has a fault. This causes volcanoes in Washington and Oregon.
What is the tectonic plate west of Oregon?
West of Oregon is the Juan de Fuca Plate.
Is pacific ring of fire both a major earthquake zone and a volcano zone?
Yes, it is. It is, essentially, the border of Pacific plate (and smaller bordering ocean plates, such as the Juan de Fuca off the coasts of northern California, Oregon, Washington and southern British Columbia and the Nazca off the coast of South America) and bordering continental plates (The Eurasian plate, the North American plate, the South American plate, the Australian Plate and smaller plates such as the Phillipine plate).
What geologic conditions exist in small town on the coast of Oregon that might cause a tsunami?
The conditions do not exist in the town itself, but off the coast of Oregon. About 85 miles off the coast of Oregon is a boundary between two tectonic plates. Here, the small Juan de Fuca Plate is colliding with and sliding under the North American Plate. These plates periodically release energy in the form of earthquakes. In some cases, these earthquakes may be accompanied by vertical movement of the ocean floor, which can displace ocean water and trigger tsunamis.
What continental plate is Oregon in?
The North American plate.
What minor plate is the largest?
South American plate
What is the minor plate?
Juan de Fuca Plate
