The processes of the Earth deformation can be revealed by means of diverse methods of investigations. The seasonal distribution of surface loading, the earthquake cycle, volcanic processes (eruptions, dike intrusions, induced seismic activity), near surface motions (landslides, induced and natural superficial subsidence/collapse).
Recently, major earthquakes in Sumatra (2004, Mw 9.2), Maule (2010, Mw 8.8), Haiti (2010, Mw 7.1) and Tohoku (2011, Mw 9.0) have exposed the impact of such events and the need for better understanding of Earth deformation processes. These events illustrate the geodynamic complexities that include subduction zones and giant earthquakes, continental faults and depth versus surface deformation, the seismic cycle and seismotectonics of active zones, magmatism processes and crustal deformation. The observation techniques, methods and data analysis need the Earth observation systems and reference frames that include remote sensing and surface and satellite gravity observations
This session is conducted in the frame of the WEGENER consortium*) and we seek submissions that emphasize multidisciplinary studies of Earth deformation using geodetic techniques (GPS, InSAR, LiDAR, space/air/terrestrial gravity, ground-based geodetic observations), complementary tectonic and geophysical observations, and modeling approaches focusing on the European-Mediterranean and Northern African regions. We also welcome contributions discussing the realization and outcomes of Supersites in the frame of the GEO initiative, as well as fundamental studies of natural and induced physical phenomena, strategies to develop early warning and rapid response systems.
