We define the geometric and kinematic characteristics of fault activated during M w = 6.3, 6 April 2009 L'Aquila earthquake, from modeling Envisat COSMO‐SkyMed (the first ever X‐band interferogram inverted for a coseismic dislocation study) DInSAR interferograms. Our best‐fit solution main shock is represented by normal ∼16 km long ∼12 wide, with small right‐lateral component, dipping 47°SW maximum slip ∼90 cm. Although seismic probably ended at 1 depth, updip projection plane corresponds to...

In case of a seismic event, fast and draft damage map the hit urban areas can be very useful, in particular when epicentre earthquake is located remote regions, or main communication systems are damaged. Our aim to analyse capability sensing techniques for detection explore combined use radar (SAR) optical satellite data. Two studies have been proposed: Izmit (1999; Turkey) Bam (2003; Iran). Both affected by strong earthquakes causing heavy extended settlements close epicentre. Different...

Destructive earthquakes challenge Earth Observation (EO) systems to demonstrate their usefulness in supporting intervention and relief actions. The use of EO data a disaster context has been widely investigated from theoretical point view, but only recently the developed methods seem have reached near operational use.

We measured ground displacements before and after the 2009 L'Aquila earthquake using multi-temporal InSAR techniques to identify seismic precursor signals. estimated deformation its temporal evolution by exploiting a large dataset of SAR imagery that spans seventy-two months sixteen mainshock. These satellite data show up 15 mm subsidence occurred beginning three years This within two Quaternary basins are located close epicentral area filled with sediments hosting multi-layer aquifers....
We study land subsidence processes and the associated ground fissuring, affecting an active graben filled by thick unconsolidated deposits means of InSAR techniques fieldwork. On 21 September 2012, Ciudad Guzmán (Jalisco, Mexico) was struck fissures about 1.5 km length, causing deformation roads propagation in adjacent buildings. The field survey showed that alignment is coincident with escarpments produced on 19 1985, when a strong earthquake magnitude 8.1 central Mexico. In order to detect...
<p>On May 20 and 29, 2012, two earthquakes of magnitudes 5.9 5.8 (Mw), respectively, their aftershock sequences hit the central Po Plain (Italy), about 40 km north Bologna. More than 2,000 sizable aftershocks were recorded by Isti-tuto Nazionale di Geofisica e Vulcanologia (INGV; National Institute Geophysics Volcanology) Seismic Network (http://iside.rm.ingv.it/). The sequence was generated pure compressional faulting over blind thrusts western Ferrara Arc, it involved a 50-km-long...
Abstract The coseismic slip distribution of the M w 9.0 2011 Tohoku‐Oki earthquake has been estimated by inverting near‐field onshore and offshore geodetic data, using Green's function calculated with a 3‐D finite element (FE) model. FE model simulates several geophysical features subduction zone that hosted rupture surface event. These include geometric configuration material properties tectonic system, precise irregular surface, an free according to topography bathymetry. A along interface...
This paper shows the main outcomes of Puyehue volcano (Chile) eruption monitoring by means multisensor remote sensing instruments working from thermal infrared (TIR) to microwave (MW) spectral range. Thanks use Synthetic Aperture Radar (SAR) and Moderate Resolution Imaging Spectroradiometer (MODIS), evolution was observed, capturing deformations edifice, lava extension, as well information on ash gas emitted. On one hand, SAR Interferometry applied ENVISAT-ASAR data allowed estimation...
<p>The 24 August 2016 earthquake very heavily struck the central sector of Apennines among Lazio,Umbria, Marche and Abruzzi regions, devastating town Amatrice, nearby villages other localities along Tronto valley. In this paper we present results macroseismic field survey carried out using European Macroseismic Scale (EMS) to take heterogeneity building stock into account. We focused on epicentral area, where geological conditions may also have contributed severity damage. On whole,...
Abstract The 2016–2017 seismic sequence, in central Italy, was caused by the Mt. Vettore‐Mt. Bove active fault system, which generated three mainshocks, largest one of M w 6.6, on 30 October 2016. On 18 January 2017, four 5–5.5 events nucleated Campotosto fault. is considered as potentially responsible for ~6.6 and a gap. structure also 5.4 aftershock during 2009 L'Aquila sequence. We here combined new geological/geomorphological field data, 1945 aerial photographs interpretation, geodetic...
The global sea-level rise (SLR) projections for the next few decades are basis developing flooding maps that depict expected hazard scenarios. However, spatially variable land subsidence has generally not been considered in current projections. In this study, we use geodetic data from navigation satellite system (GNSS), synthetic aperture radar interferometric measurements (InSAR) and tidal stations to show combined effects of SLR along coast between Catania Marzamemi, south-eastern Sicily...
The Indonesian earthquake took place on 26 December 2004 at 00:58 GMT (moment magnitude 9.3) in the Indian Ocean, offshore west coast of Sumatra, a depth about 30 km. This is one largest past 100 years, comparable only with those Chile (1960) and Alaska (1964). originated subduction zone Burma plates, moving relative velocity 6 cm/year. aftershocks were distributed along plate boundary 1000–1300 km between Sumatra Andaman Islands. Some hours after destructive tsunami followed hit coastlines...
