Local stresses, dyke arrest and surface deformation in volcanic edificesand rift zones
dyke injection dyke arrest crustalstresses crustal layering surface deformation volcanic hazard
2015/9/15
Field studies indicate that nearly all eruptions in volcanic edifices and rift zones are supplied with magma through
fractures (dykes) that are opened by magmatic overpressure. While (inferred) dyke ...
Databases of surface wave dispersion
seismic tomography upper mantle lateral resolution azimuthal anisotropy
2015/9/10
Observations of seismic surface waves provide the most important constraint on the elastic properties of the Earths
lithosphere and upper mantle. Two databases of fundamental mode surface wave disper...
Effects of surface irregularities on intensity data from laser scanning: an experimental approach
Terrestrial Laser Scanner Intensity Incidence Angle
2015/9/1
The results of an experiment carried out with the aim to investigate the role of surface irregularities on the intensity data provided by a terrestrial laser scanner (TLS) survey are reported here. De...
Surface roughness of pyroclastic deposits at Mt. Etna by 3D laser scanning
surface roughness pyroclastic deposits Laser 3D
2015/9/1
The terrestrial 3D Laser Scanning technique has been applied to analyse the surface roughness of pyroclastic deposits on volcanic surfaces at Mt. Etna. This technique allowed the construction of high ...

Ground deformation Differential Interferometry
2015/9/1
This paper presents a comprehensive overview of the surface deformation retrieval capability of the Differential
Synthetic Aperture Radar Interferometry (DInSAR) algorithm, referred to as Small BAsel...
The 1997-1998 Umbria-Marche post-earthquakes investigation:Perspective from a decade of analyses and debates on the surface fractures
Umbria-Marche seismic sequence coseismic surface fractures moderate size earthquakes post-earthquake emergency response
2015/9/1
The Umbria-Marche sequence represents the first case in Italy for which the surface effects of a moderate seismic event (5re systematically investigated and documented. Surface fractures attri...
Cooling of a channeled lava flow with non-Newtonian rheology: crust formation and surface radiance
Rheology Magmas Thermodynamics Lava flow Effusion rate
2015/8/27
We present here the results from dynamical and thermal models that describe a channeled lava flow as it cools by radiation. In particular, the effects of power-law rheology and of the presence of bend...
A 3000-year record of surface-rupturing earthquakes at Günalan: variable fault-rupture lengths along the 1939 Erzincan earthquake-rupture segment of the North Anatolian Fault, Turk
paleoseismology North Anatolian Fault fault segment
2015/8/26
The North Anatolian Fault is a ca. 1200-km-long, right-lateral, strike-slip fault that forms the northern boundary of the Anatolian plate. A damaging sequence of earthquakes ruptured almost the entire...
The May-June 2012 Ferrara Arc earthquakes (northern Italy):structural control of the spatial evolution of the seismic sequence and of the surface pattern of coseismic fractures
Seismogenic source Coseismic fracturing Compressional tectonics Ferrara arc earthquake Po Plain
2015/8/26
The Ferrara 2012 seismic sequence was characterized by two main compressional events, which occurred on May 20 and 29, 2012, with Mw 6.1 and Mw 6.0, respectively (quick Regional Centroid Moment Tensor...

In the 1980's, from an analysis of satellite images, Russian scientists reported on a short-term thermal infrared radiation enhancement that occurred before some medium-to-large earthquakes in central...
Fluorescence Efficiency of Surface Seawater as a Function of Excitation and Emission Wavelength
Excitation and Emission Wavelength Surface Seawater
2015/8/19
Fluorescence of natural waters has often been employed in attempts to quantify dissolved chromophores. However, it has not always been recognized that the intensity of fluorescence obtained from a giv...
A MULTIRESOLUTION AND OPTIMIZATION-BASED IMAGE MATCHING APPROACH: AN APPLICATION TO SURFACE RECONSTRUCTION FROM SPOT5-HRS STEREO IMAGERY
High resolution mapping satellite imagery
2015/8/17
This paper addresses the multi-resolution implementation of a Cox&Roy optimal flow image matching algorithm. This
minimization algorithm aims at solving the surface reconstruction problem formalized...
The fact that we may soon be able to virtually walk (or run) through our data is exciting. I have often felt that support for oceanography would be better if people could see ocean currents, river plu...
