The effects of dynamic processes in the Earth's crust on the propagation of seismic waves have been observed in numerous investigations. Observables include changes of propagation velocities, anisotropy and attenuation that are monitored using micro seismicity, repeating earthquakes, active sources or ambient noise. Potential processes that affect seismic wave propagation are earthquake triggering and relaxation, volcano and landslide dynamics as well as production from hydrocarbon reservoirs and geothermal fields.

To contribute to the physical understanding of the relation between causative processes that alter local material characteristics and the seismic observables we invite papers on new observational field and laboratory investigations as well as studies that model these effects.
