What is the largest earthquake to ever occur from shifting in a rift/fracture zone, such as the East Africa rift, the Mendocino Fracture zone, the Tjörnes Fracture Zone, ect.? Also if you have the date and general locations of these earthquakes, that would help a lot. Thank you!

East Africa rift: The largest earthquake to have occurred in the rift system since 1900 had a magnitude of about 7.6. Most earthquakes within the East African rift system occur as the result of either normal faulting or strike-slip faulting.

Mendocino fracture zone, also known as Mendocino transform fault.This zone, which extends approximately 190 kilometers into the eastern Pacific, was the source of the September 1, 1994, earthquake estimated at between 6.8 and 7.2 in magnitude.http://www.coast-nopp.org/visualization_modules/physical_chemical/basin_coastal_morphology/principal_features/deep_ocean/oceanic_ridges/california.html
Tjornes –at least 5.8. A magnitude 5.8 earthquake which struck the Tjornes Fracture Zone near Husavik, Iceland's whale-watching capital, in September 2002
