We investigate a large geodetic data set of interferometric synthetic aperture radar (InSAR) and GPS measurements to determine the source parameters for three main shocks 2016 Central Italy earthquake sequence on 24 August 26 30 October (Mw 6.1, 5.9, 6.5, respectively). Our preferred model is consistent with activation four coseismic asperities belonging SW dipping normal fault system associated Mount Gorzano-Mount Vettore-Mount Bove alignment. Additional slip, equivalent Mw ~ 6.1–6.2...
In this work we present and discuss new geodetic velocity strain-rate fields for the Euro-Mediterranean region obtained from analysis of continuous GNSS stations. We describe procedures methods adopted to analyze raw GPS observations >4000 stations operating in Euro-Mediterranean, Eurasian African regions. The goal massive is monitoring Earth’s crust deformation response tectonic processes, including plate- micro-plate kinematics, geodynamics, active tectonics, earthquake-cycle, but...
We provide a new 3-D GPS velocity field solution of the Euro-Mediterranean area computed at Centro Nazionale Terremoti (CNT) division Istituto di Geofisica e Vulcanologia (INGV). The available raw data since 1993, have been fully reprocessed by three different software and final is obtained combining independent solutions in least squares sense. input are treated as stochastic samples true loosening reference frame constraints associated variance-covariance matrix. proposed approach allows...
On April 6, 2009, 01:32:39 GMT, the city of L'Aquila was struck by a Mw 6.3 earthquake that killed 307 people, causing severe destruction and ground cracks in wide area around epicenter. Four days before main shock we augmented existing permanent GPS network with five stations Central Apennine Geodetic Network (CaGeoNet) bordering basin. The maximum horizontal vertical coseismic surface displacements detected at these 10.39 ± 0.45 cm −15.64 1.55 cm, respectively. Fixing strike direction...
Since 2004, a continuous Global Positioning System (GPS) network is operated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) to investigate active tectonic processes in Italy and surrounding regions, which are still largely debated. This important infrastructure, named Rete Integrata GPS (RING) network, consists about 130 stations deployed all over Italy. The development realization of stable monumentation, integration with seismological instruments choice both satellite...
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...
The goal of this article is the illustration new functionalities VADASE (Variometric Approach for Displacements Analysis Stand-alone Engine) processing approach. was presented in previous works as an approach able to estimate real time velocities and displacements a global reference frame (ITRF), using high-rate (1 Hz or more) carrier phase observations broadcast products (orbits, clocks) collected by stand-alone GNSS receiver, achieving accuracy within 1–2 cm (usually better) over intervals...
<p>In May-July 2012, a seismic sequence struck broad area of the Po Plain Region in northern Italy.

Understanding natural variations of Rn (222Rn) concentrations is the fundamental prerequisite using this radioactive gas as a tracer, or even precursor, processes, including earthquakes. In work, in groundwater were continuously measured over seven-month period, during 2017, Giardino Spring, Italy, together with levels nearby well installed into fractured regional aquifer. Data processed to reduce noise, and then analyzed produce Fourier spectra levels. These compared spectrum tidal forces....
<p>We used continuous Global Positioning System (GPS) measurements to infer the fault geometry and amount of coseismic slip associated August 24, 2016 Mw 6 Amatrice earthquake. We realized a three dimensional displacement field by combining different geodetic solutions generated independent analyses raw GPS observations. The deformation described in this work aims at representing consensus solution that minimizes systematic biases potentially present individual solutions. Because...
[1] Two critical items in the energetic budget of a seismic province are strain rate, which is measured geodetically on Earth's surface, and yearly number earthquakes exceeding given magnitude. Our study based one most complete recent catalogs Italian rate map implied by multiyear velocity solution for permanent GPS stations. For each 36 homogeneous zones we use appropriate Gutenberg-Richter relation, seismicity catalog, to estimate associated with mechanical work due coseismic displacement....
<p>We used High-Rate sampling Global Positioning System (HRGPS) data from 52 permanent stations to retrieve the coseismic dynamic displacements related 2016 August 24 <em>M<sub>w</sub></em> 6.0 Amatrice earthquake. The HRGPS position time series (named hereinafter "GPSgrams") were obtained with two different analysis strategies of raw GPS measurements (Precise Point [PPP] and Double-Difference [DD] positioning approaches using Gipsy-Oasis II TRACK (GAMIT/GLOBK)...
The recent development of GNSS networks in Italy makes it possible to define an increasingly detailed spatial and temporal resolution the ongoing crustal deformation visualize complex interplay between different orogens Africa-Eurasia collision zone. We have analyzed all available GPS raw data time span 1998-2013 obtaining coordinate series a common reference frame. finally produced velocity field providing picture kinematics pattern Italian area. horizontal velocities with respect Eurasia...
Abstract The Adria microplate is the foreland of oppositely verging Apennines and Alps or Dinarides fold‐thrust belts associated to related subduction zones. Along its western margin, plate hosts active Northern accretionary prism, which buried under Adriatic Sea Po Plain. interpretation seismic reflection profiles borehole data allowed us define geometry transition from belt undeformed foreland. Moreover, continuous GPS (CGPS) offshore hydrocarbon platforms anchored seabed northern allow...
Abstract The fast individuation and modeling of faults responsible for large earthquakes are fundamental understanding the evolution potentially destructive seismic sequences. This is even more challenging in case buried thrusts located offshore areas, like those hosting 9 November 2022 Ml 5.7 (M w 5.5) M L 5.2 that nucleated along Apennines compressional front, northern Adriatic Sea. Available on- (from hydrocarbon platforms) geodetic observations seismological data provide robust...
We find that geodetic strain rate (SR) integrated with the knowledge of active faults points out hazardous seismic areas are those lower SR, where possibly approaching end cycle. SR values estimated from GPS velocities at epicentral large historical earthquakes in Italy decrease increasing elapsed time, thus highlighting more prone to reactivation. have modelled an exponential relationship between and time since last largest earthquake, differencing according their fault rupture style. Then,...
<p>Since 1999, we have repeatedly surveyed the central Apennines through a dense survey-style geodetic network, Central Geodetic Network (CAGeoNet). CAGeoNet consists of 123 benchmarks distributed over an area ca. 180 km × 130 km, from Tyrrhenian coast to Adriatic coast, with average inter-site distance 3 5 km. The network is positioned across main seismogenic structures region that are capable generating destructive earthquakes. Here, show horizontal GPS velocity field both and...
