The San Gregorio-Hosgri fault trend is a component of the San Andreas fault system on which there may have been about 115 kilometers of post-early Miocene right-lateral strike slip. If so, right slip on the San Andreas and San Gregorio-Hosgri faults accounts for most of the movement between the Pacific and North American plates since mid-Miocene time. Furthermore, the magnitude of right slip on a Paleogene proto-San Andreas fault inferred from the present distribution of granitic basement is reduced considerably when Neogene-Recent San Gregorio-Hosgri right slip is taken into account.
圣格雷戈里奥-霍斯格里断层走向是圣安德烈亚斯断层系统的一部分，中新世早期之后可能有大约 115 公里的右旋走滑。如果是这样，圣安德烈亚斯断层和圣格雷戈里奥-霍斯格里断层的右旋滑移占从中新世中期以来太平洋板块和北美板块之间运动的大部分。此外，当考虑新近纪-现代圣格雷戈里奥-霍斯格里右旋滑移时，从现今基岩花岗岩分布推断出的古近纪原圣安德烈亚斯断层的右旋滑移量大大减少。
