Keywords: large dormant landslides Northern Apennines olistostromes active tectonics syn-sedimentary tectonics rock-falls ground collapse

(a) Dating and physical correlation of marker horizons in the palaeo-autochthonous successions of Mugello and Alta Romagna, with location of equivalent time-surfaces in the semi-allochthonous successions. (b) Structural and physiographic reconstruction of the Miocene Apennine front, from the study of olistostromes and their peculiar sedimentary drapes. (c) Chronological reconstruction of the Apennine deformation, based on: reactivations and offsets involving the Liguria nappe overthrust surface; intersection relationships between compressive structures and extensional structures; relationships between recent uplift and extensional structures. (d) Analysis of movement type, evolution and causes of some large dormant landslides in the Northern Apennines and the Southern Alps, with special emphasis on their historical and/or present-day reactivations. (e) Elaboration of geological data for the geomechanical modeling of large rock falls. (f) Geological and geotechnical hypotheses on the development of ground collapse structures (pseudo-sinkholes) in the fluvial ridges of the Po Plain.

The previously described research subjects encompass geologic and geomorphologic surveys in the Apennine chain of Emilia-Romagna, Tuscany and Marche. Field work and air-photo interpretation are carried out according to current methodologies of geologic mapping and elaboration. If possible, seismic profiles and borehole logs are used to calibrate cross-sections. The subsurface data about landslides come from informal participation to drilling and monitoring works, commissioned by public agencies to professionals. The subsurface data used for the study of ground surface collapses mainly come from penetration tests, in part published by the Regione Emilia-Romagna, in part commissioned by private persons to professionals. All research subjects require deep integration between field data and literature data. In the analysis of large dormant landslides, special attention is paid to interpretation of historical documents.
