Faults display a seamless spectrum of slip behavior: from fast motion during regular earthquakes, which radiate high frequency acoustic waves, to slow slip and aseismic creep. In the crust, complex feedback between brittle fracturing, viscous deformation, and fluid-rock interactions results in a wide variety of fault structures, from the grain (micrometer) to the crustal (kilometer) scale. Elucidating the interplay between different deformation mechanisms and assessing the associated structures have the potential to explain the variability in slip behavior. To provide meaningful physical models for fault slip, it is therefore fundamental to bridge several scales of observations and to integrate seismology, structural geology, experimental rock deformation, microstructural investigation, and petrology. Interdisciplinary and synergetic community effort is key for the advancement of earthquake physics. We invite scientists of any expertise to contribute and particularly welcome works that integrate different approaches to explore the phenomenology of slow-to-fast unstable fault motion.
