Journal ArticleDOI
A thermal pressurization model for the spontaneous dynamic rupture propagation on a three‐dimensional fault: 1. Methodological approach
Andrea Bizzarri,Massimo Cocco +1 more
TL;DR: In this paper, the role of frictional heating and thermal pressurization on earthquake ruptures was investigated by modeling the spontaneous propagation of a 3D crack on a planar fault governed by assigned constitutive laws and allowing the evolution of effective normal stress.
Journal ArticleDOI
Slip‐weakening behavior during the propagation of dynamic ruptures obeying rate‐ and state‐dependent friction laws
Andrea Bizzarri,Massimo Cocco +1 more
TL;DR: In this paper, the authors model the traction evolution and shear stress degradation near the tip of a propagating dynamic rupture by solving the elastodynamic equation for a 2D in-plane fault obeying rate and state-dependent friction laws and adopting a finite difference numerical method.
Journal ArticleDOI
On the slip‐weakening behavior of rate‐ and state dependent constitutive laws
Massimo Cocco,Andrea Bizzarri +1 more
TL;DR: In this article, the authors study the dynamic traction behavior within the cohesive zone during the propagation of earthquake ruptures adopting rate and state-dependent constitutive relations, and propose a scaling relation between these two lengthscale parameters which prescribes that D0eq/L ∼ 15.
Journal ArticleDOI
A thermal pressurization model for the spontaneous dynamic rupture propagation on a three‐dimensional fault: 2. Traction evolution and dynamic parameters
Andrea Bizzarri,Massimo Cocco +1 more
TL;DR: In this paper, Bizzarri et al. investigated the dynamic traction evolution during the spontaneous propagation of a 3D earthquake rupture governed by slip-weakening or rate-and state-dependent constitutive laws and accounting for thermal pressurization effects.
Journal ArticleDOI
Earthquake triggering by static and dynamic stress changes
TL;DR: In this paper, the authors investigated the effect of static and dynamic stress changes in promoting earthquake failures on secondary faults and showed that the effects of both types of stress changes are quite different.
