Abstract
The study of active structures offshore requires very-high resolution seismic
imaging in order to observe the most recent layers below sea floor. In the other
hand, high penetration methods are necessary to observe deeper reflections for understanding
the evolution of the structure throughout the time. The aim of our study
is to establish the seismic potential of the offshore segment of the Carboneras Fault,
Eastern Betics, based on multiscale seismic imaging. Three different scale methods
have been acquired and are compared here: very-high-resolution sub-bottom profiler
TOPAS, very-high-resolution single-channel seismic (Sparker) and high-resolution
multi-channel seismic. From seismic profiles, faulted Quaternary layers suggest
that the Carboneras Fault is active. Sediment coring and dating analysis are used
to consider ages for key reflectors observed in TOPAS profiles, and a change in the
vertical slip-rate through the Quaternary is inferred.
