Active tectonics and palaeoseismological study along the El Asnam thrust fault (associated with M 7.3 earthquake in 1980, Algeria) which is among the first analyses of thrust-related surface faulting and folding in the Mediterranean regions.
Pioneering works in the identification of active faults in intraplate Europe and the Rhine graben with development of palaeoseismic studies in regions with low-level of seismicity. In particular, combining the use of micro-topography, shallow geophysics and trenching in active faulting studies.
Development of earthquake geology, palaeoseismic and archaeoseismic studies in different tectonic domains (North African Atlas, North Anatolian fault, East Anatolian fault and Dead Sea fault) and comparison between regions with slow active deformation and regions with fast seismic slip release.
Conceptual framework in the understanding of the long-term faulting behavior in earthquake-prone regions, coastal tectonics and seismic sources of tsunami. Studies of faults in regions with the potential for large or moderate earthquakes and related physical characteristics.
