Abstract

Summary

The Central Apennines in Italy exhibit geological complexity due to polyphase tectonic activity. As a well-known example of a Tertiary fold-and-thrust belt in the active Mediterranean region, the Apennines underwent post-orogenic extensional tectonics from late Pliocene to the present. This prolonged extensional activity shaped the landscape, forming extensional basins related to normal fault activity. These basins are important archives for understanding the region’s tectonic evolution, crucial for assessing earthquake hazards in an area prone to M6-7 earthquakes. Geophysical imaging, particularly high resolution seismic reflection profiling, plays a key role in understanding subsurface structures. Combining reflection and refraction seismic methods proves advantageous for shallow imaging of complex structures like tectonic basin, since tomographic velocity models aid lithological classification and interpretation of seismic images. This contribution presents two case studies using high-resolution seismic imaging in the Campo Felice and Fucino basins, focusing on basin architecture, fault geometries, sedimentary infill, and evolution. The study aims to highlight differences in results quality between basins with distinct geological settings, emphasizing the imaging of active faults. The presented seismic sections offer insights into the subsurface structures of Mt. Cefalone, San Benedetto, and Trasacco faults.
