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 length of the fault rupture was about 1,000 kilometers (620 miles), with an average slip of 20 meters (66 ft).

The earthquake caused a tsunami which struck the west coast of North America and the coast of Japan.
