The contribution of structural geology, experimental rock deformation and numerical modelling to an improved understanding of the seismic cycle: Preface to the Special Volume “Physico-chemical processes in seismic faults”

► Earthquakes are a fundamental manifestation of brittle faulting in the Earth’s crust.
► Field, experimental and theoretical investigations complement seismological–geophysical studies of the seismic cycle.
► This preface of the Special Volume introduces nineteen contributions on physico-chemical processes in seismic faults.
► The Special Volume celebrates the contribution made by Prof. Shimamoto in earthquake-related faulting phenomena.
