CONCLUSIONS

During the VOLTAIRE 2002 cruise, despite technical failures and bad weather, capable to invalidate our results, we have acquired a network of MCS lines, that will contribute in better defining the shallow structure and neotectonics of this area located off the SW corner of the Iberian Peninsula. We have focused the investigation upon three main topics:

1.

the Guadalquivir Bank: lines VOL01, VOL02, VOL03, VOL04, VOL05;

2.

the active faults located in the Horseshoe Abyssal Plain, the Horseshoe fault after Zitellini et al. (2001) and an eastern thrust that seems to follow the contour of the SW Iberia continental margin: lines VOL13, VOL15, VOL14, VOL16;

3.

the southeastern tectonic termination of the Marquês de Pombal structure: lines VOL17, VOL18, VOL19, VOL20.

These MCS profiles will integrate the preexisting data set and will allow us to study the geometry of the faults related to the above mentioned regional tectonic structures. The accurate knowledge of the geology of these structures, coupled with a constant monitoring of the regional seismicity, will contribute in assessing their potenzial hazard on the coasts of SW Portugal and NW Morocco.
