Dynamics, interactions and delays of the 2019 Ridgecrest rupture sequence

T Taufiqurrahman, AA Gabriel, D Li, T Ulrich, B Li… - Nature, 2023 - nature.com
The observational difficulties and the complexity of earthquake physics have rendered
seismic hazard assessment largely empirical. Despite increasingly high-quality geodetic …

Dynamic viability of the 2016 Mw 7.8 Kaikōura earthquake cascade on weak crustal faults

T Ulrich, AA Gabriel, JP Ampuero, W Xu - Nature communications, 2019 - nature.com
We present a dynamic rupture model of the 2016 Mw 7.8 Kaikōura earthquake to unravel the
event's riddles in a physics-based manner and provide insight on the mechanical viability of …

Brittle fracture theory describes the onset of frictional motion

I Svetlizky, E Bayart, J Fineberg - Annual Review of Condensed …, 2019 - annualreviews.org
Contacting bodies subjected to sufficiently large applied shear will undergo frictional sliding.
The onset of this motion is mediated by dynamically propagating fronts, akin to earthquakes …

Coupled, physics-based modeling reveals earthquake displacements are critical to the 2018 Palu, Sulawesi tsunami

T Ulrich, S Vater, EH Madden, J Behrens… - Pure and Applied …, 2019 - Springer
Abstract The September 2018, M_w M w 7.5 Sulawesi earthquake occurring on the Palu-
Koro strike-slip fault system was followed by an unexpected localized tsunami. We show that …

Hypocentral dependent shallow slip distribution and rupture extents along a strike-slip fault

S Yao, H Yang - Earth and Planetary Science Letters, 2022 - Elsevier
Natural faults feature heterogeneities in geometry, material properties, and stress
distributions, posing great challenges in predicting fault slip behaviors. Among these factors …

Bimodal seismicity in the Himalaya controlled by fault friction and geometry

L Dal Zilio, Y van Dinther, T Gerya, JP Avouac - Nature communications, 2019 - nature.com
There is increasing evidence that the Himalayan seismicity can be bimodal: blind
earthquakes (up to Mw~ 7.8) tend to cluster in the downdip part of the seismogenic zone …

Extreme scale multi-physics simulations of the tsunamigenic 2004 sumatra megathrust earthquake

C Uphoff, S Rettenberger, M Bader… - Proceedings of the …, 2017 - dl.acm.org
We present a high-resolution simulation of the 2004 Sumatra-Andaman earthquake,
including non-linear frictional failure on a megathrustsplay fault system. Our method exploits …

PM Mai, D Schorlemmer, M Page… - Seismological …, 2016 - pubs.geoscienceworld.org
Finite‐fault earthquake source inversions infer the (time‐dependent) displacement on the
rupture surface from geophysical data. The resulting earthquake source models document …

Additional shear resistance from fault roughness and stress levels on geometrically complex faults

Z Fang, EM Dunham - Journal of Geophysical Research: Solid …, 2013 - Wiley Online Library
The majority of crustal faults host earthquakes when the ratio of average background shear
stress τb to effective normal stress σeff is τb/σeff≈ 0.6. In contrast, mature plate‐boundary …
