Fig. 4

Eight representative depth profiles of vertically-oriented earthquake clusters, lateral aftershock projection, and interpreted fault traces. (a-c) Lines 1–3 are perpendicular to the Moxi segment of the XSHF (f1), and (d) Line 4 is perpendicular to the Daduhe fault (f2). Aftershocks within a 2 km range on both sides of the profiles are projected on the diagrams. (e-h) Lines 5–6 and 7–8 are perpendicular to two newly identified faults, f3 and f4, to the west of the mainshock. Aftershocks within a 1.5 km range on both sides of the profiles are projected on the diagrams. The gray areas represent the data range, and the red lines represent the fault traces on the profiles.
