Session 4. Intracontinental deformation and slowly deforming areas

Conveners: N. d'Agostino, J. Jackson, A. Walpersdorf, L. Bastos

Today, the archives of space-geodetic observations (such as GNSS, InSAR) cover time intervals of more than 20 years and now enable us to recognize extremely slow crustal deformation. Careful analyses of these observations yield highly precise 3D velocity fields. Moreover, they are also starting to detect long-term transient deformations even in regions of low tectonic activity.

These results highlight features such as the activity of slow faults, but also crust-mantle interactions and more generally the presence of volume forces, as well as surface processes, for example related to hydrology or climatology. New approaches are needed to identify and understand the sources of moderate or rare seismic activity in continental regions and slowly deforming areas. In this sense, in regions where records of past seismic activity are poorly preserved, geodetic estimates of tectonic deformation improve the assessment of seismic hazard.

We encourage contributions based on a multi-technique approach integrating space-geodetic techniques with seismology, paleo-seismology, gravimetry, historical evidence, geological fieldwork and geomorphology, as well as other types of information (such as sea level, hydrology, meteorology) to improve our understanding of slow and intracontinental deformation.
