The study of the temporal evolution of deformation, strain, and stress in the Earth's crust is of fundamental importance if we want to understand the mechanisms that trigger the seismicity. Of particular interest are transient deformations, since sources of strain can induce both small seismic activity and large earthquakes. The best way we have to observe and describe these transient deformations is through geodetic and seismic data. Today, depending on the region under study, a quite accurate modeling and interpretation of the deformation sources causing transient events can be achieved thanks to the high spatial and temporal density of geodetic and seismic measurements. In light of these developments, we invite contributions describing and/or modeling transients of both tectonic (e.g., slow slip events, post-seismic deformation) and non-tectonic origin (e.g., hydrological, thermal, anthropogenic) in geophysical time series from both plate boundaries and interiors, with particular interest on slowly deforming regions. We also welcome works describing new methods and algorithms to improve the detection of transient deformation episodes, primarily from geodetic (e.g., GPS, InSAR, strainmeters) and seismic data and their correlation with other observables (e.g., GRACE).
