| Zusammenfassung |
| A landslide, to the west of Montemurro (a small village in southern Italy),
has recently caused damage to buildings and other infrastructure in an
urbanized area; as a result the development of new economic activities has
been prohibited. The landslide phenomenon started in the last century and
has been studied since the 1990s using classical geotechnical methods;
however the sliding body continues to move. This paper presents the results
of a study carried out using field surveys, geognostic investigations and
TDR (time domain reflectometry) measurements in order to reconstruct the
stratigraphy of the sediments involved and to further understand the
geological and geomorphological context of the slope. This study is part of
a larger multidisciplinary project, the results of which will also be
presented in this paper. The landslide (rotational slide in the upper
sector, developing into a translational slide in the lower part) affects
Quaternary continental clastic deposits resting on a bedrock formed by
Tertiary siliciclastic sediments of the Gorgoglione Flysch. TDR measurements
did not show any significant movement during the period monitored (January
2013–January 2014). Slip zone geometries were hypothesized using
inclinometric measurements taken from previous studies, stratigraphic data
and geomorphological interpretations of topographic scarps. Feedback from
monitoring will confirm this hypothesis. |
