Steadily moving semi-infinite fracture in plane poroelasticity
Evgenii Kanin, Andreas Möri, Dmitry Garagash +1
We present a boundary integral formulation for steadily propagating semi-infinite plane strain tensile and shear fractures in poroelastic media. By combining fundamental solutions…
Linear and nonlinear stability of rate-and-state faults
Robert C. Viesca, Dmitry I. Garagash
Models of faults incorporating slip rate- and state-dependent friction have reproduced phenomena from spontaneous slow, aseismic slip to earthquake-generating dynamic rupture. Nume…
Propagation of Elongated Fluid-Driven Fractures: Rock Toughness vs. Fluid Viscosity
Dmitry I. Garagash
This paper studies the effect of the rock fracture toughness on the propagation of elongated fluid-driven fractures. We use the `tough PKN' model of Sarvaramini and Garagash (2015)…
Ground Motion Characteristics of Cascading Earthquakes in a Multiscale Fracture Network
Kadek Hendrawan Palgunadi, Alice-Agnes Gabriel, Dmitry Igor Garagash +3
Fault zones exhibit geometrical complexity and are often surrounded by multiscale fracture networks within their damage zones, influencing rupture dynamics and near-field ground mo…
Fault-size dependent fracture energy explains multi-scale seismicity and cascading earthquakes
Alice-Agnes Gabriel, Dmitry I. Garagash, Kadek H. Palgunadi +1
Earthquakes vary in size over many orders of magnitude, yet the scaling of the earthquake energy budget remains enigmatic. We propose that fundamentally different "small-slip" and…
Rupture Dynamics of Cascading Earthquakes in a Multiscale Fracture Network
Kadek Hendrawan Palgunadi, Alice-Agnes Gabriel, Dmitry Igor Garagash +2
Fault-damage zones comprise multiscale fracture networks that may slip dynamically and interact with the main fault during earthquake rupture. Using 3D dynamic rupture simulations…
