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...
Abstract On 24 August 2016, a M w 6.0 normal‐faulting earthquake struck central Italy, causing about 300 fatalities and heavy damage. A geological survey collected the coseismic effects observed at surface in order to evaluate two competing hypotheses their nature: faulting versus gravitational deformation. We find that most significant effect is 5.2 km long alignment of ground ruptures along Mount Vettore Fault System. These are independent from lithology, topography, morphology, change...
<p>Since the beginning of ongoing Amatrice seismic sequence on August 24, 2016, initiated by a Mw 6.0 normal faulting earthquake, EMERGEO Working Group (an INGV team devoted to earthquake aftermath geological survey) set off investigate any coseismic effects natural environment. Up now, we surveyed about 750 km2 and collected more than 3200 observations as differently oriented tectonic fractures together with intermediate- small- sized landslides, that were mapped in whole area. The...
Volcanic islands are often affected by ground displacement such as slope instability, due to their peculiar morphology. This is the case of Ischia Island (Naples, Italy) dominated Mt. Epomeo (787 m a.s.l.), a volcano-tectonic horst located in central portion island. study aims follow long temporal evolution deformations on island through interferometric analysis satellite SAR data. Different datasets, acquired during Envisat, COSMO-SkyMed and Sentinel-1 missions, for first time processed...
Abstract Volcanic‐intrusive complexes often formed along lateral slab edges as a consequence of subduction‐induced mantle flow. We investigate this process in the southern Tyrrhenian Sea by integrating multibeam bathymetry, seismic‐reflection data, regional magnetic anomalies and seismological data. The interpretation data highlights presence magmatic intrusions that locally reach seafloor forming volcanic edifices. Chimneys, lava flows, laccoliths are observed beneath surrounding volcanoes....
Acoustic Emissions (AE) are effective for monitoring ground deformation and temporal variation of its porosity. AE complementary to seismic information, related the same area, though earthquakes focus on observational evidence concerned with substantially different space- time-scales. information is pertinent (i) either geodynamically stable areas, where it probes diurnal thermal and/or tidal deformation, (ii) or areas provides some as yet unexploited precursors, (iii) volcanic appears...
Aeromagnetic data collected between the Aeolian volcanoes (southern Tyrrhenian Sea) and Calabrian Arc (Italy) highlight a WNW‐ESE elongated positive magnetic anomaly centered on Capo Vaticano morphological ridge (Tyrrhenian coast of Calabria), characterized by an apical, subcircular, flat surface. Results forward inverse modeling show 20 km long 3–5 wide magnetized body that extends from sea floor to about 3 below level. The properties this are consistent with those medium highly evolved...
Salina Island (Italy) in the central Aeolian chain is northernmost volcanic structure of an elongated ridge on a regional shear zone with NNW‐SSE strike‐slip faults and second‐order N‐S NE‐SW faults. Modeling high‐resolution, low‐altitude aeromagnetic data collected 2003 2005 using volcanological constraints reveals inner volcanoes surrounding marine regions. Regional negative anomalies overlie E‐W sedimentary basins related to early Pliocene‐Pleistocene opening southern Tyrrhenian Sea....
The active Vulcano Island (Southern Tyrrhenian Sea) represents the southernmost portion of a NW‐SE elongated volcanic ridge that includes also Lipari and Salina islands. is affected by regional, to N‐S striking fault system. elaboration analysis data from three high‐resolution aeromagnetic surveys carried out between 1999 2004 on offshore allow us recognize high intensity magnetic anomalies related centers/conduits or shallow intrusions. Previously unreported submarine vents have been...
<p>Ischia island represents the westernmost portion of Phlegraean Volcanic District (Campania Region, Italy) and is characterized by presence Mt. Epomeo, a giant centrally located resurgent volcanic horst. This horst controlled fault systems magmatic dynamics able to generate recurrent seismicity. Such seismicity, associated with terrains different degrees erodibility, makes Ischia highly subjected several ground instability phenomena such as landslides. multidisciplinary study aimed...
Newly acquired high-resolution, low-altitude aeromagnetic data over Vulcano Island and Southwestern Lipari in the Southern Tyrrhenian Sea resolve major volcanic features area associated with past present activity. The magnetic character changes amplitude frequency from south-east to north-west. Primordial Vulcano, Lentia Complex, Piano Caldera units, Fossa deposits, currently active La cone Vulcanello represent main phases on Island. They show a distinct anomaly pattern, whereas prior this...
A scientific debate has developed in the last few years as to whether a 130 m diameter sag pond surrounded by saddle‐shaped rim and neighboring smaller sags from Sirente Plain (Abruzzi, Italy) represent only known Italian meteoritic crater field, mud volcano, or an anthropogenic feature. To decipher nature of landforms, we carried out geophysical geochemical investigations. Geoelectric profiles document two karstified shelf carbonate ridges lying at 10–40 depth below calcareous lacustrine...
This study presents magnetic anomaly data from a new high-resolution, low-altitude helicopter-borne survey recently collected on and offshore Tenerife in the Canary Archipelago. The Italian Istituto Nazionale di Geofisica e Vulcanologia (INGV) collaboration with Museo Nacional de Ciencias Naturales of CSIC Spain conducted 2006. for surrounding marine areas were processed into digital total intensity anomalies geomagnetic epoch 2006.4. Relative to previously available higher altitude data,...
Geomorphometric parameters (slope, aspect, valley depth, and areal density of cones) derived from a moderate resolution digital elevation model with grid spacing 100 m are used in an attempt to interpret the tectonic/structural features related surface deformation Auca Mahuida volcanic terrain (Neuquén Basin, Argentina). The (2.03–0.88 Ma) is southernmost field Payenia province, Andean foreland. foreland subjected E–W compression eastward migration N–S striking thrust front Andes....
The Auca Mahuida volcano (2.03–0.88 Ma) located east of the Andean thrust front in Neuquén basin (Argentina) hosts an oil system thermogenic origin and is affected by NW–SE striking-faults. Intrusive bodies underlying Jurassic sediments constitute reservoir rocks. Aeromagnetic data collected area detected multiple dipolar magnetic anomalies, many which have reverse polarity. Palaeomagnetic measurements on rock samples field together with available age determinations indicate that reversely...
