Where is the Cascadia plate?

The Cascadia subduction zone (also referred to as the Cascadia fault) is a convergent plate boundary that stretches from northern Vancouver Island in Canada to Northern California in the United States.

How much does the Cascadia plate boundary move?

This plate is moving northeastward relative to North America along a convergent plate boundary such that the Juan de Fuca plate is subducting beneath the North American plate at the Cascadia trench at an approximate rate between 9.8 and 13.8 feet per 100 years.

What areas are affected by the Cascadia fault?

The Cascadia Subduction Zone (CSZ) “megathrust” fault is a 1,000 km long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino California.

What type of plate boundary is Cascadia?

The Cascadia Subduction Zone, extending from northern California through western Oregon and Washington to southern British Columbia, is a type of convergent plate boundary. Two parallel mountain ranges have been forming as a result of the Juan de Fuca Plate subducting beneath the edge of North America.

Where is the subduction zone of the Cascadia plate?

Cascadia Subduction Zone. The Cascadia Subduction Zone (CSZ) “megathrust” fault is a 1,000 km long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino California. It separates the Juan de Fuca and North America plates. New Juan de Fuca plate is created offshore along the Juan de Fuca ridge.

Where does the Cascadia fault begin and end?

The Cascadia subduction zone (also referred to as the Cascadia fault) is a convergent plate boundary that stretches from northern Vancouver Island in Canada to Northern California in the United States. It is a very long, sloping subduction zone where the Explorer, Juan de Fuca, and Gorda plates move to the east and slide below

Are there recordings of the last Cascadia earthquake?

While there are not seismological recordings of the last Cascadia earthquake, seismologists can simulate ground shaking using information about the fault and observations from other subduction zone earthquakes.

How big was the earthquake in Cascadia in 1700?

The 1700 quake occurred two centuries before seismometers were invented and widely installed. We therefore do not have direct measurements of how large the earthquake was.
