Deep ductile shear localization facilitates near-orthogonal strike-slip faulting in a thin brittle lithosphere [PDF]
, 2020 Some active fault systems comprise near-orthogonal conjugate strike-slip faults, as highlighted by the 2019 Ridgecrest and the 2012 Indian Ocean earthquake sequences.

Useful predictions ahead of large earthquakes and lessons learned for future progress
Geodesy and Geodynamics, 2020 A significant basis for this article is the outcome of 4 multinational research projects which were carried out in South-West Iceland from 1988–2006, focusing on crustal processes that preceded two magnitude-6.6 earthquakes in June 2000.

Foreshock properties illuminate nucleation processes of slow and fast laboratory earthquakes
Nature Communications, 2023 Understanding the connection between seismic activity and the earthquake nucleation process is a fundamental goal in earthquake seismology with important implications for earthquake early warning systems and forecasting.

Spectral-element simulations of long-term fault slip: Effect of low-rigidity layers on earthquake-cycle dynamics [PDF]
, 2011 We develop a spectral element method for the simulation of long-term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.

Self-similar slip pulses during rate-and-state earthquake nucleation [PDF]
, 2009 For a wide range of conditions, earthquake nucleation zones on rate- and state-dependent faults that obey either of the popular state evolution laws expand as they accelerate. Under the “slip” evolution law, which experiments show to be the more relevant

Properties of Dynamic Earthquake Ruptures With Heterogeneous Stress Drop [PDF]
, 2006 Earthquake rupture is a notoriously complex process, at all observable scales. We introduce a simplified semi-dynamic crack model to investigate the connection between the statistical properties of stress and those of macroscopic source parameters ...

Earthquake nucleation in weak subducted carbonates
Nature Geoscience, 2016 Ocean-floor carbonate- and clay-rich sediments form major inputs to subduction zones, especially at low-latitude convergent plate margins. Therefore, knowledge of their frictional behaviour is fundamental for understanding plate-boundary earthquakes.

A window into the complexity of the dynamic rupture of the 2011 Mw 9 Tohoku-Oki earthquake [PDF]
, 2011 The 2011 Mw 9 Tohoku-Oki earthquake, recorded by over 1000 near-field stations and multiple large-aperture arrays, is by far the best recorded earthquake in the history of seismology and provides unique opportunities to address fundamental issues in ...

Journal of Asian Earth Sciences: X, 2023 The seismically active Saurashtra horst is located within the intraplate volcanic continental margin of western India. The region is prone to moderate and low-magnitude earthquakes within the depth range of ∼ 3 to ∼ 24 km.
