The magnitude of a megathrust earthquake is proportional to length of the rupture along the fault. The Cascadia subduction zone, which forms the boundary between the Juan de Fuca and North American plates, is a very long sloping fault that stretches from mid-Vancouver Island to Northern California.

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 ...
For decades, scientists have warned about the potential of the Cascadia Subduction Zone, a megathrust fault that runs offshore along the coast from northern Vancouver Island to Cape Mendocino ...
A map of the Juan de Fuca plate with noted seismic incidents, including the 2001 Nisqually earthquake. The Juan de Fuca plate is bounded on the south by the Blanco fracture zone (running northwest off the coast of Oregon), on the north by the Nootka Fault (running southwest off Nootka Island, near Vancouver Island, British Columbia) and along the west by the Pacific plate (which covers most of ...
The fault runs offshore along the West Coast from Northern California to northern Vancouver Island in Canada. It is capable of producing magnitude-9.0 earthquakes and tsunami waves about 100 feet ...
And there was the catastrophic mega-tsunami of 1700, originating from a magnitude 9 earthquake over the Cascadia fault system, which runs offshore from Northern California to Vancouver Island for ...
A great subduction earthquake, such as the magnitude M 9 1700 Cascadia earthquake, caused by slippage of the entire Cascadia subduction zone, from approximately Cape Mendocino in northern California to Vancouver Island in British Columbia.
Cascadia subduction zone, Vancouver Island. In 1996, a team of researchers linked the orphaned 1700 tsunami in Japan with a magnitude 9 earthquake and tsunami in North America in a Trans-Pacific reunion. [7]: 94–95 [8] [9] Scientists "dated the earthquake to the evening of January 26, 1700" and approximated its size as magnitude 9.
