Seismic transmission tomography: determination of the elastic properties of building structures (some examples)
applied geophysics cultural heritage inversion seismic tomography
2015/9/29
This paper is a general review on seismic transmission tomography considering data acquisition and processing. Some questions on linear and non linear inversions are tackled, and advice given on the c...
Evidence of Apulian crustal structures related to low energy seismicity (Murge - Southern Italy)
Bouguer anomalies Murgian plateu low energy seismicity tensional structures
2015/9/28
The discovery of recent co-seismic sedimentary structures and the detection of low energy seismic activity in the Murgian plateau (Apulia - Southern Italy) motivated a more detailed examination of the...
This paper deals with some fundamental considerations regarding the behaviour of geotechnical structures under seismic loading. First a complete definition of the earthquake disaster risk is provided,...
Collapse modes of structures under strong motions of earthquake
collapse mode damage concentration P-d effect flexible-stiff mixed structure
2015/9/25
Under strong motion earthquakes, structures receive various types of damage. The most fatal damage is the loss of lateral strengths of a structure. The loss of lateral resistance causes a total collap...
2001 Bhuj-Kachchh earthquake:surface faulting and its relation with neotectonics and regional structures,Gujarat,Western India
surface rupture Kachchh earthquake thrust fault
2015/9/16
Primary and secondary surface deformation related to the 2001 Bhuj-Kachchh earthquake suggests that thrusting movement took place along an E-W fault near the western extension of the South Wagad Fault...
Buried volcanic structures in the Gulf of Naples (Southern Tyrrhenian Sea, Italy) resulting from high resolution magnetic survey and seismic profiling
Gulf of Naples Southern Tyrrhenian Sea magnetic anomalies high-resolution reflection seismics volcanic structures
2015/9/10
In this paper we present a correlation between volcanic structures and magnetic anomalies in the Gulf of Naples (Southern Tyrrhenian Sea) based on high resolution magnetic profiling. A densely spaced ...
Comparison between active stress field and tectonic structures in Northern Italy, Lombardy Region
borehole breakout analysis active stress field tectonic structures Po Plain Italy
2015/9/10
The aim of this work is to understand the complex pattern of active stress field orientations revealed by borehole
breakout analysis with respect to the tectonic structures in a wide region of Northe...
Searching for the effects of the May-June 2012 Emilia seismic sequence (northern Italy):medium-depth deformation structures at the periphery of the epicentral area
Emilia 2012 earthquake Seismic effect Faulting Seismic reflection survey
2015/8/26
In 2012, a seismic sequence occurred in the lowlands of the Emilia-Romagna Region (northern Italy), between the borders of the Modena, Ferrara and Bologna Provinces. It consisted of seven mainshocks (...
INTEGRATION OF TERRAIN MODELS AND BUILT-UP STRUCTURES USING CADTYPE EULER OPERATORS
Triangular Irregular Network (TIN) models, Euler Operators
2015/3/9
Until recently terrain models were developed in a GIS, and built-up structures were modelled using a CAD system. Extending the
current “2.5D” TIN model by incorporating CAD functions is a necessary ...
Lithospheric-scale structures in New Guinea and their control on the location of gold and copper deposits
Lithospheric-scale structures New Guinea location of gold copper deposits
2015/1/6
The locations of major gold and copper deposits on the island of New Guinea are considered by many to be controlled by a series of transfer faults that strike N–S to NE–SW, perpendicular to the long a...
The sensitivity of GNSS measurements in Fennoscandia to distinct three-dimensional upper-mantle structures
GNSS measurements Fennoscandia three-dimensional upper-mantle structures
2015/1/6
The sensitivity of global navigation satellite system (GNSS) measurements in Fennoscandia to nearby viscosity variations in the upper mantle is investigated using a 3-D finite element model of glacial...
The Relationship Between Upper Mantle Anisotropic Structures Beneath California, Transpression, and Absolute Plate Motions
The Relationship Between Upper Mantle Anisotropic Structures California Transpression Absolute Plate Motions
2014/4/10
We calculated SKS splitting parameters for the California Integrated Seismic Network. In southern California, we also estimated splitting in the upper 100 km using azimuthal anisotropy determined fr...
Shaking table tests on strengthening of masonry structures against earthquake hazard
Shaking table tests strengthening masonry structures earthquake hazard
2010/10/20
Turkey and neighborhood countries like Greece and Iran are situated on an active earthquake region. Masonry type structures are very common on these countries, especially on the rural areas. During t...
A catalogue of nonlinear vortex structures associated with acoustic-gravity perturbations in the Earth's atmosphere is presented. Besides the previously known Kelvin-Stewart cat's eyes, dipolar and tr...
Statistical analysis of Stromboli VLP tremor in the band [0.1–0.5] Hz:some consequences for vibrating structures
Statistical analysis Stromboli VLP tremor band [0.1–0.5] Hz vibrating structures
2009/11/9
We analyze time series of Strombolian volcanic tremor, focusing our attention on the frequency band [0.1–0.5] Hz (very long period (VLP) tremor). Although this frequency band is largely affected by no...
