Fig. 3: Microstructural observations within all samples.

(Top) Number of completely fractured [filled bars] and partially fractured [open bars] grains. “Locked samples” (blue) are from Pallett Creek, “Creeping samples” (orange) are from Ferrum, and “Control samples” include aseismic samples from Ferrum and no co-seismic slip from Pallett Creek inside the fault zone, and samples outside the fault zone at Pallett Creek [~650 m away]. Each bar provides counts for a single sample. EQ earthquakes, FZ fault zone. (Bottom) Check mark indicates grain deformation observed.
