First results from the CROP-11 deep seismic profile, central Apennines, Italy: evidence of mid-crustal folding

The CROP-11 deep seismic profile across the central Apennines, Italy, reveals a previously unknown, mid-crustal antiform here interpreted as a fault-bend fold-like structure. The seismic facies and gravity signature suggest that this structure consists of low-grade metamorphic rocks. Geomorphological, stratigraphic and tectonic evidence in the overlying shallow thrusts suggests that this structure developed in early to mid-Messinian time and grew out of sequence in late Messinian– Pliocene time. The out-of-sequence growth may reflect a taper subcriticality stage of the Apenninic thrust wedge, which induced renewed contraction in the rear.Published583–586ope

The Bisaccia landslide: a case of deep seated gravitational movement reactivated by earthquake.

This paper is concerned with a case of deep-seated gravitational slope deformations wich affected the town of Bisaccia (Southern Italy), in consequence of the disastrous earthquake of the 23rd November 1980. Historical documents indicate how the movement was reactivated also during past earthquakes
