The microstructure and mineralogy of volcanic rocks is varied and complex, and their
mechanical behaviour is similarly varied and complex. This review summarises recent …

Much work has been undertaken quantifying the abundance of phyllosilicate clay minerals
in soils, sediments and rocks of Earth's crust. However, no detailed global compilation of …

Clay-rich fault rocks have long been recognized to host distinctive fabric elements, and fault
rock fabric is increasingly thought to play a fundamental role in fault mechanical behaviour …

We report macroscopic stick‐slip events in saw‐cut Westerly granite samples deformed
under controlled upper crustal stress conditions in the laboratory. Experiments were …

Earthquakes are the result of a combination of (1) physico-chemical processes operating in
fault zones, which allow ruptures to nucleate and rock friction to decrease with increasing …

We present a stochastic ground‐motion model for Switzerland. A model for the far‐field
Fourier amplitude spectra of earthquakes is first proposed, constrained by ground motions …

Rate‐and‐state friction (RSF) laws are extensively applied in fault mechanics but have a
largely empirical basis reflecting only limited understanding of the underlying physical …

Fluids are pervasive in fault zones cutting the Earth's crust; however, the effect of fluid
viscosity on fault mechanics is mainly conjectured by theoretical models. We present friction …

To determine the role of strain localization during dynamic weakening of calcite gouge at
seismic slip rates, single-slide and slide–hold–slide experiments were conducted on 2–3 …

To investigate differences in the frictional behavior between initially bare rock surfaces of
serpentinite and powdered serpentinite (“gouge”) at subseismic to seismic slip rates, we …
