Large continental earthquakes necessarily involve failure of multiple faults or segments. But these same critically-stressed systems sometimes fail in drawn-out sequences smaller over days years instead. These two modes have vastly different implications for seismic hazard and it is not known why fault one mode the other, what controls termination reinitiation slip protracted sequences. A paucity modern observations has hampered our understanding to-date, but a series three Mw>6 from August...
We provide a database of the coseismic geological surface effects following Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one strongest seismic events to occur in Europe past thirty years, causing complex ruptures over an area >400 km2. The originated from collaboration several European teams (Open EMERGEO Working Group; about 130 researchers) coordinated by Istituto Nazionale di Geofisica e Vulcanologia. observations were collected performing detailed field...
<p>We present some preliminary results on the mapping of coseismically-induced ground ruptures following Aug. 24, 2016, Central Italy earthquake (Mw 6.0). The seismogenic source, as highlighted by InSAR and seismological data, ruptured across two adjacent structures: Vettore Laga faults. We collected field data breaks along whole deformed area different scenarios on-fault coseismic displacement arise from these observations. To north, fault, surface faulting can be mapped quite...
Abstract This study explores the seismotectonics of Kachchh in western India, a region with low-to-moderate strain rate and history significant earthquakes, notably 1819, Mw 7.8 Allah Bund, 2001, 7.6 Bhuj. Despite its substantial seismic risk, comprehensive studies on Kachchh’s seismogenic sources are scarce. is attributed to concealed nature active structures, hindering definitive age constraints paleoseismological research. Our research comprises detailed paleoseismic analysis...
This paper documents evidence of surface faulting associated with the 6 April 2009 moderate-sized earthquake (ML 5.8, Mw 6.3) in central Apennines Italy, which caused major damage to town L’Aquila and its surroundings. Coseismic ruptures were mapped for a minimum distance 2.6 km along Paganica fault, fault still poorly investigated relative other active faults nearby, bound much wider range fronts. Surface rupture length (SRL) maximum displacement parameters (2.6 10–15 cm, respectively) are...
Abstract. We present the first paleoseismological results along Fiandaca Fault, source of 26 December 2018, Mw 4.9 Fleri earthquake. excavated two exploratory trenches coseismic surface ruptures at Collegio site. Analysis trench walls allow identifying, besides 2018 event, historical faulting events. The youngest one occurred in period 1281–1926 CE, and most likely during the1894 oldest one, previously unknown, Early Middle Ages (757–894 CE). This paleoseismic evidence strongly suggest...
Recently, Dual-Polarimetric Synthetic Aperture Radar (SAR) has been shown to be effective for large-scale snow cover monitoring, but it faces significant challenges when applied finer resolutions, which are crucial applications such as avalanche forecasting. In this study, we propose a novel mathematical model retrieve properties from Sentinel-1 SAR data, leveraging variations in the Vegetation Index (DpRVIc). We introduce Snow (SIsar), quantifies signal depolarization occurring within...
The processes that rule coupling/decoupling and rupture mechanisms along the plate interface in deep portions of active subduction zones are largely inferred from geophysical observations. These observations highlight a wide range deformation mechanism may coexist, such as: aseismic slip, episodic non-volcanic tremor slip (ETS), regular earthquakes. Despite high amount data obtained through indirect approaches, our comprehension occurring is still limited. In particular, at great depth...
The study of ancient volcanic and volcaniclastic sequences provides key insights into geodynamic processes that contributed to their evolution, as well valuable information on paleoenvironment evolution basin dynamics.The Varese area hosts a Permian magmatic complex related the igneous events characterized Southern Alps during Late Palaeozoic. While previous research has detailed petrographic, isotopic, geochronological aspects these rocks, stratigraphic studies interaction with depositional...
The Paleozoic Variscan cycle and the successive Mesozoic-Cenozoic Alpine supercontinent have shaped structural framework of central European-Mediterranean area. Nevertheless, tectonic events marking transition between two cycles are open to different interpretations. As a remnant chain, European Southern Alps stand as an ideal study area unravel geodynamic processes governing this period.Our focus is on western Alps, specifically included in Geological Map n.74 &#8220;Varese&#8221;...
Paleoseismology is a vital tool for the study of earthquake hazard and active tectonics. Its application in context Late Quaternary basaltic volcanoes encounters considerable limitations due to inherent highly dynamic nature such systems. Etna volcano, however, provides an ideal setting studies. In particular, densely populated Mt. eastern flank record frequent surface faulting earthquakes aseismic fault creep, which result significant offsets well-dated historical landforms stratigraphy,...
ABSTRACT Coseismic fault displacement is a localized source of hazard following surface-rupturing earthquakes. Here, we exploit the usefulness geological maps and traces contained therein, to predict location coseismic ruptures (CORs). We analyze five earthquakes that occurred in Italy United States, measuring (1) amount CORs along previously mapped faults (2) already actually moved during strong earthquake. These quantities are 32% ± 30% 20% 11%. The values highly variable depending on...
It is commonly believed that the Po Plain an area of low seismic hazard. This conclusion essentially a combination two factors: (1) historical record earthquakes, which shows relatively small number events moderate magnitude, and only significant occurred in Middle Ages; (2) lack ad-hoc research on geology earthquakes this area, as although many studies have highlighted local Quaternary tectonics, very few them discussed observed evidence terms In contrast, data presented present study...
<p>Since May 16, 2012, a seismic sequence has affected wide portion of the Emilia Region (northern Italy), chiefly for Modena and Ferrara Provinces. The first mainshock (Ml 5.9; focal depth, ca. 6 km) occurred on 20, with epicenter located few kilometers north Finale Emilia. A second main shock 5.8; 10 29, about 12 km west earthquake, near Medolla (Figure 1). been characterized by five other Ml ≥5 events, more than 2,300 aftershocks lower magnitude, until end July 2012. distribution...
Abstract Moderate to strong earthquakes (i.e., Mw > ~6.0) commonly produce a complex network of ground ruptures, which are responsible for significant damage. Distributed faulting can affect wide areas (tenths square kilometers), and expected displacement be estimated through probabilistic approach, considering distance from the primary fault earthquake magnitude. Other factors may have role in driving occurrence distributed faulting; nevertheless, they not adequately addressed current...
Heavy rainfall is a major factor for landslide triggering. Here, we present an inventory of 47,523 landslides triggered by two precipitation episodes that occurred in May 2023 the Emilia-Romagna and conterminous regions (Italy). The are manually mapped from visual interpretation satellite images mainly second episode (16–17 2023); entirely original, mapping supplemented with field surveys at few selected locations. main goal this paper to dataset investigate distribution respect triggering...

The Castrovillari scarps (Cfs) are located in northern Calabria (Italy) and consist of three main WSW-dipping fault resulting from multiple rupture events. At the surface, these defined by breaks slope. Despite its near-surface complexity, faults likely merge to form a single normal at about 200 m depth, which we refer as fault. We present results multidisciplinary multiscale study selected site Cfs with aim (i) characterize geometry surface depth (ii) obtain constraints on slip history....
