Abstract


This paper contains the results of a series of geophysical investigations carried out on the largest debris flow to
have taken place in Tavernole, S. Felice a Cancello (Caserta, Southern Italy). The landslide occurred in concurrence
with other catastrophic events in the Sarno Mountains in May 1998. This research project is part of a series
of geological, geomorphological and geotechnical studies whose purpose is to improve the knowledge of
this type of phenomenon. The project also tested and compared various survey methods in the sample area of S.
Felice a Cancello. Geophysical surveying allowed us to collect information regarding the physical features and
thickness of the materials affected by landslide phenomena and to verify the applicability and effectiveness of
the various indirect surveying methods adopted. The preliminary results of the study enabled us to generate a series
of suggestions which could prove useful in formulating the correct approach to this type of problem to be
adopted in ordinary professional practice. These indications concerned the type of geophysical surveying to be
conducted and, where applicable, the means of implementation. In general, seismic refraction was found to be
the best technique for collecting information on the area studied.
