Theoretical constraints on dynamic pulverization of fault

Clearly, stress concentration and high strain rate can exist locally near a propagating crack front, but the integrated quantities over a volume should remain relatively low. Dynamic ruptures in models accounting for brittle damage can provide better constraints on rupture-induced loadings and threshold values for rock pulverization.
