Fault plane solutions of crustal earthquakes in Southern Italy (1988-1995): seismotectonic implications
southern Italy focal mechanisms seismicity stress distribution
2015/9/28
The Southern Apennines and the Sicilian-Calabrian regions belong to the complex geodynamic Central Mediterranean area, which is dominated by the NNW-SSE convergence of the European and African plates ...
Earthquake fault-plane solutions and patterns of seismicity within the Umbria Region,Italy
fault-plane solution seismicity seismotectonic Italy
2015/9/8
In this paper we present a review of the seismotectonic features (an analysis of earthquake focal mechanisms and the distribution of seismicity) of the Northern Apennines, Umbria Region (Italy) in the...
Faulting mechanism of the Campania–Lucania 1980 earthquake, Italy, from high-resolution, 3D velocity structure, aftershock relocation, fault-plane solutions, and post-seismic deformation modeling
Campania-Lucania 1980 earthquake analyses of the post-seismic data
2015/8/27
This study performs a detailed reconstruction of the rupture mechanism of the 1980 Campania–Lucania (southern Italy) earthquake. This is achieved by relocation of the main event through computation of...
Using publicly available GPS solutions for fast estimations of first-order source details from coseismic deformations
GPS Coseismic deformations Source inversion Maule earthquake
2015/8/27
We here explore the potential use of publicly available GPS solutions to obtain first-order constraints on a source model immediately following an earthquake, within the limits of GPS solution timelin...
Quick regional centroid moment tensor solutions for the Emilia 2012 (northern Italy) seismic sequence
Earthquake source Seismic moment tensor Wave analysis Data processing
2015/8/26
In May 2012, a seismic sequence struck the Emilia region (northern Italy). The mainshock, of Ml 5.9, occurred on May 20, 2012, at 02:03 UTC. This was preceded by a smaller Ml 4.1 foreshock some hours ...
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...
Practical analytical solutions for benchmarking of 2-D and 3-D geodynamic Stokes problems with variable viscosity
Practical analytical solutions benchmarking of 2-D and 3-D geodynamic Stokes problems variable viscosity
2015/1/6
Geodynamic modeling is often related with challenging computations involving solution of the Stokes and continuity equations under the condition of highly variable viscosity. Based on a new analytical...
Identifying sets of acceptable solutions to non-linear,geophysical inverse problems which have complicated misfit functions
sets of acceptable solutions non-linear,geophysical inverse problems misfit functions
2009/11/16
A goal of geophysical inversion is to identify all models which give an acceptable misfit between predicted and observed data. However, because of the complexity of Earth structure, the non-linearity ...
Localized Alfvénic solutions of nondissipative and compressible MHD
Localized Alfvénic solutions nondissipative and compressible MHD
2009/11/13
Alfvénic solutions of nondissipative MHD are entirely determined by their magnetic configuration. With the supplementary assumption of incompressibility any solenoidal field can be used to construct a...
