TL;DR: In the year following the Parkfield earthquake, a maximum of at least 20 cm of displacement occurred on a 30 km section of the San Andreas fault, which far exceeded the surficial displacement at the time of the earthquake as mentioned in this paper.
Abstract: Immediately following the 1966 Parkfield earthquake a continuing program of fault displacement measurements was undertaken, and several types of instruments were installed in the fault zone to monitor ground motion. In the year subsequent to the earthquake a maximum of at least 20 cm of displacement occurred on a 30 km section of the San Andreas fault, which far exceeded the surficial displacement at the time of the earthquake. The rate of displacement decreased logarithmically during this period in a manner similar to that of the decrease in aftershock activity. After the initial high rate of activity it could be seen that most of the displacement was occurring in 4–6 day epochs of rapid creep following local aftershocks. The variation of fault displacement along the surface trace was measured and shown to be consistent with a vertidal fault surface 44 km long and 14 km deep, along which a shear stress of 2.4 bars was relieved.

TL;DR: In this article, high-resolution seismic reflection and borehole data obtained by the petroleum industry along the northwestern margin of the South China Sea permit mapping of the offshore segment of the Red River Fault in the Yinggehai Basin, as well as demonstration of the timing of its shear movement and slip reversal.

TL;DR: In this paper, the two main compressional events of the Taiwan collision correspond to similar fan-shaped distributions of maximum compressive stress trajectories, with a counterclockwise shift of 30°-50° between the two events.

TL;DR: In this article, the relative motion between the blocks varies from about 2.5 to 8 mm year−1, which is comparable to motions of crustal blocks in areas of active rifting in other parts of the world.
