Geophysical Research Letters, 2018 The 2016 Kaikoura (New Zealand) earthquake is characterized as one of the most complex multifault rupture events ever observed. We perform dynamic rupture simulations to evaluate to what extent relatively simple forward models accounting for realistic ...

Nucleation and Arrest of Dynamic Rupture Induced by Reservoir Depletion
Journal of Geophysical Research: Solid Earth, 2019 Seismic events induced by the depletion of hydrocarbon reservoirs can cause damage to housing and cause societal and economic unrest. However, the factors controlling the nucleation and size of production‐induced seismic events are not well understood ...

Earthquake Stress Drops From Dynamic Rupture Simulations Constrained by Observed Ground Motions
Geophysical Research Letters, 2020 Stress drop characterizing dynamics of earthquake rupture propagation has various definitions and measures with a yet unclear mutual relationship. We aim to reconcile this discrepancy by analyzing synthetic dynamic rupture models generated by random ...

On the evolution of elastic properties during laboratory stick-slip experiments spanning the transition from slow slip to dynamic rupture [PDF]
, 2016 The physical mechanisms governing slow earthquakes remain unknown, as does the relationship between slow and regular earthquakes. To investigate the mechanism(s) of slow earthquakes and related quasi-dynamic modes of fault slip we performed laboratory ...

Gel rupture during dynamic swelling
Soft Matter, 2021 A complex, three-stage fracture process is described for hydrogels, resulting in material failure. This process is markedly different than that observed in brittle materials, and we describe how this process varies with network architecture.

Uncertainty quantification of dynamic earthquake rupture simulations [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021 We present a tutorial demonstration using a surrogate-model based uncertainty quantification (UQ) approach to study dynamic earthquake rupture on a rough fault surface. The UQ approach performs model calibration where we choose simulation points, fit and validate an approximate surrogate model or emulator, and then examine the input space to see which ...

Journal of Geophysical Research: Solid Earth, 2023 The Húsavík‐Flatey Fault Zone (HFFZ) is the largest strike‐slip fault in Iceland and poses a high seismic risk to coastal communities. To investigate physics‐based constraints on earthquake hazards, we construct three fault system models of varying ...

Broadband Strong Ground Motion Modeling Using Planar Dynamic Rupture With Fractal Parameters
Journal of Geophysical Research: Solid Earth, 2023 Dynamic rupture modeling represents a promising physics‐based approach to strong ground motion simulations. However, its application in a broad frequency range (0–10 Hz), interesting for engineering studies, is challenging. The main reason is that widely
