How we work Research Areas Deformation monitoring in the natural environment with GPS and InSAR Very precise geodetic measurements to study geophysical processes worldwide, especially those associated with the hazards of earthquakes, volcanoes, coastal erosion and sea-level change.

Many natural hazards arise from or are associated with very small movements of the Earth's crust.
Measuring and interpreting this deformation is the key to understanding the geophysical processes at work and predicting future hazards. Precise terrestrial and satellite geodesy provides the tool to do this. Simultaneously, the driving force of geophysical study spurs further developments in geodetic analysis methods. We have for a number of years been conducting episodic GPS experiments to measure the long-term deformation of Greece . A further part of this research concerns the smaller but significant post-seismic deformation occurring in the few years after an earthquake, which provides information on the relationship between different layers in the Earth's crust.
