Influence of the Canossa-San Romano fault system on the development of the River Secchia fluvial terraces (Northern Apennines, Italy)
[En] The geomorphological features of a stretch of the River Secchia valley, which is located on the Po Plain side of the Northern Apennines (Italy), are highly influenced by the Canossa-San Romano fault system. Strath terraces covered by thin levels of fluvial and colluvial deposits are found along the banks of the R. Secchia and witness a continued, slow, intermittent tectonic uplift along the northeastern front of the Apennines. Three orders of terraces are present, which were formed through channel scour episodes interspersed with periods of relative quiescence, with channel widening and strath formation. Rates of erosion appear to increase from north to south across a natural threshold, locally known as “Rupe del Pescale” and slow down with decreasing age. A temporal reduction in erosion rates indicates a recent slowdown of the Apennine uplift, which is in disagreement with the interpretation of earlier studies. Evidence for a slowing uplift rate also comes from the Roteglia area,
