The Azores-Tunisia region is formed by the western part of the plate
boundary between Eurasia and Africa. This plate boundary presents a
complex nature due to its proximity to the pole of rotation of the
African plate. This condition produces crustal extensions and normal
faulting at the Azores archipelago, transcurrent motion with strike slip
faulting at the center part of the Azores-Gibraltar fault and at the
eastern end, from the Gulf of Cadiz to Tunisia, plate convergence with
reverse faulting. In this last part, the collision of Iberia with
northern Morocco produces complex phenomena with intermediate depth and
deep earthquakes and an extensional regime at the Alboran sea. Recently,
new evidence has been gathered in this region based on observations from
geology, geodesy, mainly through GPS measurements, seismology,
especially with the installation of broad-band stations, and other
fields of geophysics, such as paleomagnetism and gravimetry. This volume
presents a collection of papers dealing with the geological and tectonic
structure and evolution of the region and parts thereof, its seismicity
and seismotectonic implications and geodetic and paleomagnetic
observations which offer new understanding of the complex geodynamics of
this region.
