Earthquakes foreshocks and aftershocks
WebApr 12, 2024 · The relaxation process starts close to peak stress and involves both preparatory slip and foreshocks as well as aftershocks. The underlying mechanics of slip are controlled by fault roughness, system stiffness and normal stress. Aftershock generation in the natural system is strongly affected by mainshock characteristics.
