To estimate the ground motion in two-dimensional (2D), laterally heterogeneous, anelastic media, a hybrid technique has been developed that combines modal summation and finite-difference method. In calculation of local wave field owing to seismic event, both for small large epicentral distances, it is possible take into account source, path, soil effects. As practical application, we have simulated Mexico City caused by Michoacan earthquake September 19, 1985. By studying one-dimensional...
A hybrid technique, based on mode summation and finite differences, is used to simulate the ground motion induced in city of Rome by January 13, 1915, Fucino (Italy) earthquake (M L =6.8). The technique allows us take into consideration source, path, local soil effects. results numerical simulations are for a comparison between observed distribution damage Rome, computed peak acceleration, maximum response simple oscillators, so-called “total energy motion”. total good agreement with damage....
The purpose of this work is to derive a 3-D tomographic image the shear wave velocity structure crust—uppermost mantle in Aegean area using group velocities Rayleigh fundamental mode. database consists 185 regional earthquakes recorded at broad-band stations that were installed for period 6 month within framework large-scale experiment. In previous (Karagianni et al. 2002), an averaged has been determined method frequency time analysis (FTAN) each epicentre—station ray path and data used...
The strong influence of lateral heterogeneities and source properties on the spatial distribution ground motion indicates that traditional methods require an alternative when earthquake records are not available. computation broadband synthetic seismograms makes it possible, as required by a realistic modelling, to take propagation effects into account, fully utilizing large amount geological, geophysical geotechnical data, already For recent earthquakes, where observations available, is...
We revisit the 1976 Friuli earthquake sequence by combining hypocenters relocation, long period surface wave inversion, field geology and strong motion modelling. show that fault‐related folding is main active deformation which seismic energy was released during shock (Ms=6.5) some of effects reported in correspond to widespread bedding planes displacements induced flexural‐slip folding. The fault evolved from blind semi‐blind along strike showing control inherited structural on break...
We study the 1998 Bovec‐Krn mountain (Slovenia) earthquake sequence by combining hypocenters relocation, strong motion inversion, digital elevation modelling and field geology. The main shock ( M s =5.7), a 12 km right lateral strike‐slip event on Dinaric fault system, occurred sub‐vertical plane. rupture, confined between 3 9 depth, with no evidence of surface faulting, propagated bilaterally within two structural barriers. northwestern barrier is at junction Alpine structures where there...

In order to gain insight into how invert seismograms correctly estimate the details of earthquake rupturing process, we perform numerical experiments using artificial data, generated for an idealized faulting model with a very simple rupture and moment release history, solve inverse problem standard widely used inversion methods. We construct synthetic accelerograms in vicinity discrete analog Haskell‐type prescribed velocity layered medium. A constant level is released as front passes by....
Microseismic data recorded by surface monitoring arrays can be used to estimate the effective anisotropy of overburden and reservoir. In this study we inversion picked P-wave arrival times Thomsen parameter [Formula: see text] anellipticity coefficient text]. This employs an analytic equation traveltimes as a function offset in homogeneous, transversely isotropic media with vertical axis symmetry. We considered star-like distribution receivers and, for geometry, analyzed sensitivity method...
