Newly collected morphobathymetric and seismic reflection data from the Valli di Comacchio coastal lagoons, south of the Po River delta (Northeast Italy), combined with historical, remote sensing, and geodetic data highlight a complex geological evolution during the Holocene, strongly affected by anthropic control. All data allowed us to define the...

Like other sedimentary plains, the Po Plain in Northern Italy has largely subsided due to natural processes and human activities. Displacements of the Earth surface of hydrological origin are caused by groundwater changes, which in turn, are expected to be related to rainfall changes. In the Bologna metropolitan area (located in the Southeastern bo...

This paper discusses a full interferometry processing chain based on dual-orbit Sentinel-1A and Sentinel-1B (S1) synthetic aperture radar data and a combination of open-source routines from the Sentinel Application Platform (SNAP), Stanford Method for Persistent Scatterers (StaMPS), and additional routines introduced by the authors. These are used...
Article
The morphological changes of unstable areas can be identified using different methodologies that allow repeated surveys over time. The integration between the data obtained from different remote sensing and ground-based techniques, characterized by different coverage, resolution, and precision, allows to describe the kinematic motion of landslides...
Chapter
The recognition of the seismic zones most prone to next major earthquakes in Italy would considerably help the choice of the most efficient prevention plan. This work describes an attempt to gain reliable information about that problem by exploiting the knowledge about the short-term development of the ongoing tectonic processes in the study area a...

Article
The observed deformation pattern in the central-western Mediterranean area, in particular the development of the Northern, Central and Southern Tyrrhenian basins in three well distinct phases, can hardly be explained as an effect of the gravitational sinking of subducted lithosphere, a hypothesis often advanced in literature. A more plausible and c...

Conference Paper
Modern seismic ground-motion sensors have nowadays excellent response quality in terms of dynamic and band-width resolution. The weakest point in the recording of the seismic events is the spatial sampling and resolution, due to the limited number of installed sensors, often at large distances. A significant improvement in spatial resolution can be...

The Po is the largest river of Italy, it opens with a delta mouth in the Adriatic Sea and it is bounded by the Apennines to the South and by Alps to the North and West. The modern delta occupies a broad area of about 380 Km2, with a coastal extension of around 120 Km. Several industrial activities, intensive farming and important naturalistic areas...
Conference Paper
A large number of continuous GNSS (CGNSS) stations are nowadays available in Italy, this has already allowed an accurate monitoring of the horizontal and vertical kinematic pattern in the Italian peninsula in terms of linear trends. The crustal displacements can be considered as the result of several contributions: global, regional and local tecton...

The Garisenda tower in Bologna is a symbol of the city and one of the most valuable heritages of the medieval age. The tower is leaning markedly since the XIV century because of a foundation failure and its stability is nowadays under constant monitoring through many sensors. In 2013 a GNSS permanent station was installed on the top of the tower wi...
Article
Abstract The building of the Apennine belt slowed down or ceased around the Early Pleistocene. Since then, the belt has undergone strong uplift and considerable distortion. This change, from belt-normal to belt-parallel shortening, has been determined by the fact that the continental Adriatic domain (Adria) was almost completely surrounded by buoya...
Conference Paper
The present kinematic pattern in the Central and Eastern European area has been estimated analyzing the GNSS observations acquired from the sites belonging at the Central European GPS Geodynamic Reference Network (CEGRN) Consortium. This network was established in the framework of the project called CERGOP in 1994, and the first measurement campaig...
Conference Paper
It is argued that since the late Quaternary tectonic activity in the Apennines has been driven by belt-parallel compression , induced by the motion of the Adriatic plate. This regime has been accommodated by the uplift and outward extrusion of wedges in the outer sector of the belt. The relative oblique divergence between the outer (more mobile) be...
Conference Paper
GNSS permanent stations are a fundamental tool for geodynamic analysis due to their capability to produce consistent time series of coordinates with a precision of a few millimetres. The coordinates can be estimated basing on GNSS data with two different approaches: differential and point positioning. The baselines between the sites belonging the n...

Full-text available
An effective mitigation of seismic risk in Italy can hardly be obtained without a tentative recognition of few priority zones, where the limited resources available in the short term can be concentrated. A reliable recognition of the zones where the probability of major earthquakes is highest must be carried out by a deterministic approach, exploit...

Abstract It is argued that in some zones of the Northern Apennines, in particular the Rimini-Ancona thrust system, the Romagna Apennines and the Alta Valtiberina trough, the probability of major earthquakes is now higher than in other Apennine zones. This hypothesis is suggested by the comparison of the present short-term kinematics of the Romagna-...

Full-text available
This work aims to explore the ongoing tectonic activity of structures in the outermost sector of the Northern Apennines, which represents the active leading-edge of the thrust belt and is dominated by compressive deformation. We have applied the Persistent Scatterer Interferometry (PSI) technique to obtain new insights into the present-day deformat...
Article
Full-text available
It is argued that the complex tectonic pattern observed in the study area can plausibly be explained as an effect of the kinematics of the Iberia and Adria blocks, induced by the NNE ward motion of Africa and the roughly westward motion of the Anatolian-Aegean system with respect to Eurasia. These boundary conditions cause the constrictional regime...

Introduzione Il controllo ed il monitoraggio del territorio italiano richiede informazioni sempre più precise ed accurate sia nello spazio che nel tempo. Le stazioni permanenti GNSS rappresentano un importante strumento a disposizione per questo tipo di attività ed il suo crescente numero registrato negli ultimi 15 anni rendono i risultati ottenibi...
Article
Full-text available
Major seismic activity in the Northern Apennines concentrates in few zones, distributed in a peculiar way. It is argued that such context may be plausibly explained as an effect of belt-parallel shortening, which has caused oroclinal bending of the longitudinal ridges formed during the Late Miocene to Lower Pliocene evolutionary phase. The main eff...
Article
The Tuscany-Romagna-Marche-Umbria Apennines host major seismic zones that have generated several strong earthquakes. We argue that such activity is an effect of the relative motion between the outermost sector of the Romagna-Marche-Umbria units and the surrounding zones. This interpretation is consistent with the pattern of post-early Pleistocene d...

Full-text available
An attempt is made at gaining insights into the possible location of the next strong earthquake (M > 5.5) in the Italian peninsula, by considering the regularity patterns of seismic activity so far recognized in the peri-Adriatic zones (since 1400 A.D.) and their possible connection with the ongoing tectonic setting. This analysis suggests that at...

Full-text available
Some considerations are given about attempts at predicting impending earthquakes by the use of space geodetic (GPS) observations in the Italian peninsula. Both short (weeks to days) and middle/long-term (months to years) presumed precursors are considered. At present, none of the numerous published studies seems to identify significant and systemat...

Full-text available
The analysis of geodetic observations carried out by 478 continuous GPS stations in the Italian region since 2001 has allowed a fairly good definition of the ongoing horizontal velocity field with respect to Eurasia. It is argued that such evidence can provide important insights into the geody-namic context in the central Mediterranean area. Numero...

Full-text available
The evolution of the Mediterranean area since the Oligocene-Lower Miocene has been driven by the convergence of the surrounding plates. This implies that the observed deformation pattern in that region must be the most convenient shortening pattern, i.e. the one controlled by the mini- mum action principle. To understand why the fulfilment of such...
