Quantitative geomorphological and environmental analysis requires the adoption of well–defined spatial domains as basic mapping units. They provide local boundaries to aggregate environmental and morphometric variables and to perform calculations, thus they identify the spatial scale of the analysis. Grid cells, typically aligned with a digital ele...

Delineating boundaries of urban areas is no easy task, due to the inherent complexity of the problem, heterogeneity of relevant data and little consensus on how to properly measure the results. Any such delineation must eventually be cast onto administrative boundaries, an essential requirement for real-world applications. In the effort of relating...

Slope units represent surface slopes by means of polygons delimited by drainage and divide lines obtained on a digital topography. Objective slope unit delineation for a given digital elevation model is still an open issue and, often, a limitation that may dictate the use of a more traditional pixel-based approach for spatial analysis. Availability...

Rockfalls pose a substantial threat to ground transportation, due to their rapidity, destructive potential and high probability of occurrence on steep topographies, often found along roads and railway routes. Approaches for the assessment of rockfall susceptibility range from purely phenomenological methods and statistical methods, suitable for mod...

The majority of landslide susceptibility and hazard zonations are implemented with statistical methods, especially on large scales: mostly because the data needed for physical simulations are only available in small areas. Physically–based simulations for slope stability are conceptually different from widely used statistical approaches. Both metho...

We present a model for the distribution of the number of forward neutrons emitted in soft (minimum bias) and hard inelastic proton-nucleus ($pA$) scattering at the LHC. It is based on the Gribov-Glauber model for the distribution over the number of inelastic collisions (wounded nucleons) combined with a parametrization of cross section (color) fluc...

We argue that measurements of forward neutrons from nuclear breakup in inclusive high energy photon-nucleus (photon-A) scattering provide a novel complementary way to study small-x dynamics of QCD in heavy-ion ultraperipheral collisions (UPCs). Using the leading twist approach to nuclear shadowing, we calculate the distribution over the number of e...

After an earthquake event, major ground effects include landslides. In Italy, the most common type of earthquake-induced landslides are rockfalls. The assessment of the extent and magnitude of an earthquake-induced landslide event may be of importance for both preparedness and response operations. An earlier work devised a modeling chain including...

Urban geomorphology studies the landscape in cities, and changes induced by human activities to the natural landscape. Cities have different geological-geomorphological substrates, and humans as “geomorphic agents” have been operating within them in different times since the Paleolithic, threatening the Earth-surface heterogeneity and ecological su...

Urban geomorphology analyzes modifications of morphology and topography induced by human activity in cities, urban and peri-urban areas. Urban expansion modifies ecosystems, but global actions for sustainability focus on the biosphere, overlooking the role of abiotic components, embedded in and supported by the geosphere and its ecosystem services....

Landslide susceptibility shows the spatial likelihood of landslide occurrence in a specific geographical area and is a relevant tool for mitigating the impact of landslides worldwide. As such, it is the subject of countless scientific studies. Many methods exist for generating a susceptibility map, mostly falling under the definition of statistical...

We argue that measurements of forward neutrons from nuclear breakup in inclusive high energy photon-nucleus ( γ A ) scattering provide a novel way to study small- x dynamics of QCD in heavy-ion ultraperipheral collisions (UPCs). Using models for hadronic fluctuations of the real photon and neutron emission in nuclear fragmentation, we calculate the...

In this contribution, I have summarized work done in the last few years to describe rockfall susceptibility and seismically induced rockfall susceptibility and hazard in Italy. This effort required heterogeneous data, dif ferent methods and, most importantly, a wide range of skills and expertise. Therefore, the work I am going to describe resulted...

We present a new method for earthquake-triggered rockfall scenario assessment adopting ground shaking estimates, produced in near real-time by a seismological monitoring network. Its key inputs are the locations of likely initiation points of rockfall trajectories, namely, rockfall sources, obtained by statistical analysis of digital topography. In...

Geomorphodiversity refers to the variety of landforms and morphological processes characterizing the landscape. The definition of an index to quantify geomorphodiversity is a relevant step for multiple fields of Earth sciences, since it is widely accepted that the variability of the geosphere deeply influences the diversity of the biosphere. Such a...

Different approaches exist to describe the seismic triggering of rockfalls. Statistical approaches rely on the analysis of local terrain properties and their empirical correlation with observed rockfalls. Conversely , deterministic, or physically based approaches rely on the modeling of individual trajectories of boulders set in motion by seismic s...

Timely and systematic collection of landslide information after a triggering event is pivotal for the definition of landslide trends in response to climate change. On September 15, 2022, a large part of central Italy, particularly Marche and Umbria regions, was struck by an anomalous rainfall event that showed characteristics of a persistent convec...

Key advantages of modelling landslide susceptibility at the level of slope units—homogeneous landscape elements bound by drainage and divide lines—instead of grid cells have recently been highlighted. However, there has been limited investigation into the sensitivity of a slope unit landslide susceptibility approach to the characteristics of the la...

Systematic and timely documentation of triggered (i.e. event) landslides is fundamental to build extensive datasets worldwide that may help define and/or validate trends in response to climate change. More in general, preparation of landslide inventories is a crucial activity since it provides the basic data for any subsequent analysis. In this wor...

We develop a slope-unit based landslide susceptibility model using the benchmark dataset proposed in the session, located in Central Italy. As a result, we produce two susceptibility maps based on the two different landslide presence attribute fields included in the dataset. The proposed dataset is a subset of a much larger one, recently used to ob...

The road network in Central Nepal suffered blockades and damage from numerous landslides and rockfalls due to the earthquake sequence in Gorkha, Nepal, in 2015. Additionally, frequent rainstorms in the area contributed to the recurrence of rockfalls and other types of landslides, hindering road infrastructure development and environmental managemen...

We argue that the Drell–Yan process in the xA ≥ 0.15 kinematics recently studied at FNAL by the E906/SeaQuest experiment may allow to observe an analogous of the EMC effect for antiquarks. The effects of Fermi motion and energy loss are considered. The preliminary E906/SeaQuest data are inconsistent with the growth of the σA/AσN ratio expected in t...

We argue that the Drell-Yan process in the $x_A \ge 0.15$ kinematics recently studied at FNAL by the Seaquest experiment may allow to observe an analog of the EMC effect for antiquarks. The effects of Fermi motion and energy losses are considered. The preliminary Seaquest data are inconsistent with the growth of the $\sigma_A/N\sigma_N$ ratio expec...

Empirical evidence shows that climate, deforestation and informal housing (i.e. unregulated construction practices typical of fast-growing developing countries) can increase landslide occurrence. However, these environmental changes have not been considered jointly and in a dynamic way in regional or national landslide susceptibility assessments. T...

Ischia Island is a volcano-tectonic horst in the Phlegrean Volcanic District, Italy.

Landslide susceptibility corresponds to the probability of landslide occurrence across a given geographic space. This probability is usually estimated by using a binary classifier which is informed of landslide presence/absence data and associated landscape characteristics. Here, we consider the Italian national landslide inventory to prepare slope...

Physically-based simulations for slope stability are conceptually different from widely used statistical approaches. Both methods have specific advantages, depending on available data, their type and resolution and, most importantly, the aim of the study. The majority of landslide susceptibility and hazard zonations are implemented with statistical...

Ecodiversity stems from the interaction between the biosphere and the geosphere, and it is one of the necessary conditions for achieving a sustainable planet. Thus, the relationship between geodiversity and biodiversity should be clearly defined. The relationship between climate and topography in roughened mountain areas at low-latitudes, as constr...

The World Urbanization Prospects (ONU) estimates that within 2050 about 70% of the world's population will live in urban areas.

Rainfall thresholds are intensity-duration relations supposedly able to distinguish precipitation events that may or may not trigger landslides. The most common method for defining rainfall thresholds relies on observed landslides and the corresponding values of rainfall intensity and duration that caused each failure. Alternative methods to define...

Inventories of seismically induced landslides provide essential information about the extent and severity of ground effects after an earthquake.

Editorial of the special issue "Advances in Geomorphometry", published in Transactions in GIS

At variance with conventional landslide susceptibility assessment, non-susceptibility analysis aims at selecting locations in which the likelihood of landslide occurrence is null or negligible. The advantage of this approach is that it does not require estimating different degrees of likelihood outside of the locations of negligible susceptibility....
