Multi-temporal morphological analysis coupled to seismic survey of a mass movement from southern Italy: a combined tool to unravel the history of complex slow-moving landslides.
Full text linkImpressive and large-scale slow-moving landslides with a long-term evolutionary history of activity and dormancy are a common landform in the southern Apennines mountain belt. The spatial and temporal evolution of a multi-stage complex landslide located in a catchment of the frontal sector of the southern Apennine chain was reconstructed by multitemporal geomorphological analysis, near-surface seismic survey, and DEM comparison. The Tolve landslide shows a multi-decadal evolution characterized by intermittent periods of activity and dormancy. Geomorphological evidences suggest that the initial failure of the large-scale landslide has a multi-millennial age and can be related to a roto-translational movement that evolved in an earthflow. Recent evolution is associated with a major reactivation event in the middle and lower sectors of the larger complex landslide, which probably is related to a heavy rainfall event occurred in January 1972. Recent evolution is mainly associated with minor movements in the source area, toe advancements, and widespread shallow landslides along the flank of the earthflow. Our results demonstrate the need
to integrate traditional geomorphological analysis with multi-source data to reconstruct the evolution of slow-moving landslides and to identify their main predisposing and triggering factors

Full text linkTowards the creation of an Open Source HBIM tool for planning diagnostic and restoration activities: the example of the Troia Cathedral rose window
Full text linkThe aim of this work is to set up an HBIM (Heritage Building Information Model) system to facilitate the planning of diagnostic and restoration activities by bringing all archive information into a digital platform, accompanied by three-dimensional models that can be consulted and examined.
Frequently, in case of ancient buildings, reconstruct the complete history of the property is not possible, due to a lack of accessible sources. The creation of the HBIM digital tool for consulting the architectural artefact and related information was only the last phase of this work, which began with: (i) Acquisition of archive sources in order to reconstruct the history of the restoration and renovation work on the monument; (ii) Acquisition of information about the diagnostic analyses previously carried out on the monument; (iii) acquisition of data useful for the creation of a digital twin
Late Quaternary evolution of the Metaponto coastal plain, southern Italy, inferred from geomorphological and borehole data.
Full text linkA multidisciplinary study of a sector of the Ionian coastal belt, southern Italy, mainly based on two new bore- holes approximately 25 m (MSA) and 20 m (MSB) deep, was carried out in the frame of a wider geo- archaeological project. Stratigraphic and Paleoecological data, together with geomorphological observations, have been used in order to define the Late Quaternary morpho-sedimentary evolution and its relationships with tectonic and climate forcing. The analyses of core sediments and geomorphic interpretations allowed us to reconstruct the changes in depositional setting and physical landscape starting from the MIS 5.5. To this scope, new data about sedimentary facies, benthic foraminifera and ostracod assemblages, and a set of 14C ages spanning from about 33 to 15 kyr BP are here presented. All these data revealed a strong modification of the depositional setting within the coastal plain, as inferred by the presence of marine, transitional, and continental deposits, and suggest an anomalous position of sea-level reference points. Such anomalies are clustered in two homogenous arrays that can be explained only admitting a significant tectonic uplift in recent times (i.e. about 4 mm/yr over the last 15,000 years)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
