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...

Abstract On 8 September 2023 an M W 6.8 earthquake struck the High Atlas Mountains of western Morocco, about 70 km southwest from Marrakesh, causing significant devastation and casualties. In this study, we investigate a comprehensive geodetic data set, employing interferometric synthetic aperture radar measurements to assess fault segment responsible for seismic event. Our findings suggest two potential scenarios: either transpressive NNW‐dipping high‐angle (70°) related Tizi n'Test...
The 2010–2011 Canterbury sequence is a complex system of seismic events that started with M w 7.1 earthquake and continued large aftershocks dramatic consequences, particularly for the city Christchurch. We model main earthquakes using InSAR data, providing displacement maps respective modeling September 4th, 2010, February 22nd, 2011 June 13th, events. Relocated aftershocks, field GPS surveys are used to constrain models obtained by inversion data; fault slip distribution retrieved variable...

Abstract. This study presents and discusses horizontal vertical geodetic velocities for a low strain rate region of the south Alpine thrust front in northeastern Italy obtained by integrating GPS, interferometric synthetic aperture radar (InSAR) leveling data. The area is characterized presence subparallel, south-verging thrusts whose seismogenic potential still poorly known. Horizontal GPS show that this sector eastern Southern Alps undergoing ∼1 mm a−1 NW–SE shortening associated with...
The historical City of Venice, with its lagoon, has been severely exposed to repeated marine flooding since times due the combined effects sea level rise (SLR) and land subsidence (LS) by natural anthropogenic causes. Although change in this area studied for several years, no detailed scenarios have yet realized predict expected SLR coming decades on coasts islands lagoon global warming. From analysis geodetic data climatic projections Shared Socioeconomic Pathways (SSP1-2.6; SSP3-7.0...
The progressive increase of the global mean sea level due to ongoing climate change is a major topic for safeguarding and developing coastal areas. However, local rise estimates may differ considerably from ones different subsidence/uplift rates.In framework project investigating relative (RSLR) over several areas Italy, we present results Venice Lagoon. This area an exceptional case study since it has been severely exposed repeated marine flooding throughout history subsidence rates are...

We applied the Small Baseline Subset multi-temporal InSAR technique (SBAS) to two SAR datasets acquired from 2003 up 2013 by Envisat (ESA, European Space Agency) and COSMO-SkyMed (ASI, Italian satellites investigate spatial temporal patterns of land subsidence in Sibari Plain (Southern Italy). Subsidence processes (up ~20 mm/yr) were investigated comparing geological, hydrogeological, use information with interferometric results. suppose a correlation between thickness Plio-Quaternary...
The present study analyzes the sequence of 4 important earthquakes occurred in Mexico from September 2017 to February 2018, exploiting large availability InSAR data and analytical models, with a twofold goal: privede new solutions for seismogenic sources, completely independent seismological data, discuss methodological aspects related non-linear linear inverse problem. We review update an earlier study, focused on concept resolution, showing level detail achievable investigation slip...
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...

Abstract Tsunami waveform inversion is often used to retrieve information about the causative seismic tsunami source. Tide gauges record tsunamis routinely; however, compared deep‐ocean sensor data, tide‐gauge modeling more difficult due coarse/inaccurate local bathymetric models resulting in a time mismatch between observed and predicted waveforms. This can affect retrieved source model, thus limiting use of data. A method for nonlinear with an automatic optimal alignment (OTA), calculated...
