The identification of a reliable geodynamic/tectonic model for the Italian region would be extremely useful for several practical purposes, in particular for quantifying the parameters to be used for seismic hazard assessment. In this work, the AA
be reconsidered, taking into account an alternative geodynamic model that can much better explain the major tectonic events occurred in the central Mediterranean region since the late Miocene. - (NF)
A new structural setting for the central part of the External Ligurian Briançonnais (CELB) is proposed. CELB is divided into km-scale tectonic units that still preserve pre-Alpine geological features at several stratigraphic levels. Several features
indicate that the CELB tectonic evolution took place at shallow crustal levels. A gradual decrease in the intensity of deformation from the Internal Ligurian Briançonnais to CELB and Dauphinois Domain is observed, although the boundaries of these three
have been used to study the geological, geomorphological and tectonic setting of the area. The results suggest the presence of a highly mature, almost flat Brahmaputra floodplain evolved during the recent geological past, in which palaeochannels had
a very high sinuosity. Subsequent events of uplift resulted in the formation of entrenched meanders due to incision of the valley floor. The data suggest that tectonic activity along the Main Boundary Thrust (MBT) and Himalayan Frontal Thrust (HFT) during

of sediment transfer and the spatial distribution of rockslides reflect a landscape in which tectonic and geological controls on denudation are more significant than climate.
Here, based on geomorphological observations, the AA. calculate the amount of river incision and interfluve denudation in the Meuse basin upstream of Maastricht since 0·7 Ma and show that the main response to tectonic forcing was incision
. This allows to provide first-order estimates of the tectonic and climatic contributions to the denudation of the Ardennes. By comparison, the 10 Be-derived rate is overestimated, probably due to an overrepresentation of the erosion products of the rapidly

This work deals with the tectonic interpretation of an alignment of more than 300 sinkholes stretching along the Jordanian coast of the Dead Sea, Ghor Al Haditha area. Sinkholes appeared during the last decades as a consequence of the very rapid
The Gödöllő Hills, a low-relief terrain within the Central Pannonian Basin in Hungary, is characterised by moderate tectonic deformation rates. Although typical tectonic landforms are not clearly recognisable in the study area, this paper succeeded
in discriminating between tectonically controlled landforms and features shaped by fluvial erosion or deflation with no tectonic control. DEM-based morphometric parameters including elevation, slope and surface roughness, enabled the delineation of two NW-SE
areas in southern Italy with different tectonic activities and behaviours. The axial zone of Campania-Lucania Apennine and the Sila Massif in Calabria, characterized by quite different evolutionary histories, have been chosen as test areas sufficiently
