Key Points:
We document rejuvenation of the Totschunda fault, a crustal scale strike-slip fault, after a Pacific-Yakutat plate vector change at ca. 6 Ma.
The Totschunda fault became the strand of principal slip due to its new favorable orientation over the northern Eastern Denali fault.
Across the circum-Pacific many major strike-slip faults experienced modifications in response to the ca. 6 Ma Pacific plate motion change.
