From: Which is heterogeneous, stress or strength? An estimation from high-density seismic observations
Results of stress inversion for a grid point (x = 10, y = 9, z = − 2) away from the mainshock fault. Rectangles are estimated fault planes projected onto the horizontal and two vertical sections. The upper edges of fault planes are indicated by thick colored edges, which represent the normalized shear stress on the fault plane based on color. Black, blue, green, and red indicate normalized shear stress of 0–0.2, 0.2–0.3, 0.3–0.4, and 0.4–0.5, respectively. Observed and calculated slip directions are shown by black (short) and red (long) bars at the center of the rectangle, respectively. Diameters and colors of circles represent magnitudes and misfits (difference between observed and calculated slip directions), respectively
