Rapid neuronet inversion of 2D magnetotelluric data for monitoring of geoelectrical section parameters
magnetotelluric inverse problem neural network EM monitoring
2015/9/2
The inverse MagnetoTelluric (MT) operator is approximated by means of the Neural Network (NN). The methodology of the NN interpretation in classes of the geoelectrical sections described by the hundre...
Inversion of synthetic geodetic data for the 1997 Colfiorito events:clues on the effects of layering,assessment of model parameter PDFs,and model selection criteria
data inversion geodesy coseismic displacement
2015/9/1
The 1997 September-October Umbria-Marche sequence has been extensively studied in the past by analyzing coseismic displacement data (GPS, leveling, SAR). Here we focus on synthetic data representative...
Shear-wave velocity structure at Mt. Etna from inversion of Rayleigh-wave dispersion patterns (2 s < T < 20 s)
Mount Etna Rayleigh-wave dispersion S-wave velocity modeL Non-linear inversion Triangle method
2015/8/28
In the present study, we investigated the dispersion characteristics of medium-to-long period Rayleigh waves (2 s < T < 20 s) using both single-station techniques (multiple-filter analysis, and phase-...
Fault-plane solutions from moment-tensor inversion and preliminary Coulomb stress analysis for the Emilia Plain
Emilia 2012 earthquakes Moment tensors Focal mechanisms Coulomb static stress
2015/8/26
We investigate the seismicity occurred in the Po area, in the period July 2011-June 1012, by means of moment tensor and we use our set of revised focal mechanisms - computed for M> 3.7 earthquakes - t...
Full three-dimensional relocation and tomographic inversion of the 1977-2008 earthquakes in north-eastern Italy:a feasibility study
3D Relocation Tomography
2015/8/18
In a regional seismological network, the estimation of the epicenter is usually robust, especially for events inside or close to the network boundaries. In contrast, the hypocentral depth is very sens...
The 2009 L’Aquila earthquake coseismic rupture: open issues and new insights from 3D finite element inversion of GPS, InSAR and strong motion data
GPS open issues and new insights
2015/8/17
We present a Finite Element inverse analysis of the static deformation
field for the Mw= 6.3, 2009 L’Aquila earthquake, in order to infer the rupture
slip distribution on the fault plane. An univoca...

2015/8/14
We present a Finite Element inverse analysis of the static deformation field for the Mw= 6.3, 2009 L’Aquila earthquake, in order to infer the rupture slip distribution on the fault plane. An univocal ...
Dynamic emission tomography - regularization and inversion
Emission tomography subtracting the poison radon pathology emission source static pathological inverse
2015/8/11
The problem of emission tomography, inverting the attenuated Radon transform, is moderately ill-posed if the unknown emission source is static. Here we consider the case where the emission source is d...
A Model for the Reflectance of Thin Layers, Fronts, and Internal Waves and Its Inversion
Thin Layers Fronts Internal Waves
2015/8/6
The interplay of physical and biogeochemical processes in the ocean can result in well-defined vertical gradients and maxima in biological properties. When these gradients and maxima exist near the se...

Fully probabilistic seismic source inversion – Part 1: Efficient parameterisation
Earthquake source inversion seismology non-linear uncertainty parameters the bayesian
2015/1/6
Seismic source inversion is a non-linear problem in seismology where not just the earthquake parameters themselves but also estimates of their uncertainties are of great practical importance. Probabil...
Study on the limitations of travel-time inversion applied to sub-basalt imaging
travel-time inversion sub-basalt imaging
2015/1/5
The difficulties of seismic imaging beneath high velocity structures are widely recognised. In this setting, theoretical analysis of synthetic wide-angle seismic reflection data indicate...
Magnetic Field Delocalization and Flux Inversion in Fractional Vortices in Two-Component Superconductors
