Laboratory studies on electrical effects during volcanic eruptions
Experimental volcanology explosive volcanism magma fragmentation contact electricity electrical effects
2015/10/8
This laboratory study reports on electrical phenomena during the explosive eruption of a basaltoid silicate melt. Contact electricity is produced in the phase of thermo-hydraulic fracturing of magma d...
Self-oscillations in rocks,results of laboratory experiments
self-oscillations mechanoelectricself-oscillator transformations rocks
2015/9/14
The method of generation of self-oscillations in rocks is developed here. Self-oscillations arise as a result of direct and inverse mechanoelectric transformations without an external generator. Labor...
Laboratory activity for a new procedure of MIVIS calibration and relative validation with test data
radiometric calibration MIVIS atmospheric correction MODTRAN
2015/9/7
Remotely sensed data, recorded by means of the MIVIS hyperspectral scanner in the framework of the research activity of the CNR Institutes IIA-LARA and IMAA, have been calibrated to reflectance values...
The Mallet Project: from an earthquake laboratory to laboratories on the territory
1857 Basilicata earthquake Environmental education Historical landscape History of seismology Robert Mallet
2015/8/26
On December 16, 1857, an earthquake wreaked havoc across a huge area of the regions of Basilicata and Campania (Val d’Agri and Vallo di Diano). More than 180 villages in an area of over 20,000 km2 suf...
The dynamics of laterally variable subductions: laboratory models applied to the Hellenides
laterally variable subductions laboratory models
2015/1/5
We designed three-dimensional dynamically selfconsistent laboratory models of subduction to analyse the relationships between overriding plate deformation and subduction dynamics in the upper mantle.
Seismic imaging of sandbox experiments – laboratory hardware setup and first reflection seismic sections
Simulated sandbox sandbox models simulation technology seismic physical model the earthquake the piezoelectric sensors seismic imaging
2015/1/5
With the study and technical development introduced here, we combine analogue sandbox simulation techniques with seismic physical modelling of sandbox models. For that purpose, we designed and develop...
3-D thermo-mechanical laboratory modeling of plate-tectonics: modeling scheme, technique and first experiments
3-D thermo-mechanical laboratory modeling plate-tectonics
2014/12/31
We present an experimental apparatus for 3-Dthermo-mechanical analogue modeling of plate tectonic processes such as oceanic and continental subductions, arccontinent or continental collisions.
Challenges for forecasting based on accelerating rates of earthquakes at volcanoes and laboratory analogues
Time series analysis Creep and deformation Volcano seismology Statistical seismology
2014/5/19
‘Mean-field’ models have been proposed as falsifiable hypotheses for the acceleration in earthquake rate and other geophysical parameters prior to laboratory rock failure and volcanic eruptions. Impor...
Correlation of pre-earthquake electromagnetic signals with laboratory and field rock experiments
Correlation pre-earthquake electromagnetic signals laboratory and field rock experiments
2010/10/21
Analysis of the 2007 M5.4 Alum Rock earthquake near San José California showed that magnetic pulsations were present in large numbers and with significant amplitudes during the 2 week period leading u...
Anomalous diffusion in geophysical and laboratory turbulence
Anomalous diffusion in geophysical laboratory turbulence
2009/11/16
We present an overview and some new results on anomalous diffusion of passive scalar in turbulent flows (including those used by Richardson in his famous paper in 1926). The obtained results are based...
Turbulent thermal diffusion of aerosols in geophysics and in laboratory experiments
Turbulent thermal diffusion aerosols geophysics laboratory experiments
2009/11/11
We discuss a new phenomenon of turbulent thermal diffusion associated with turbulent transport of aerosols in the atmosphere and in laboratory experiments. The essence of this phenomenon is the appear...
Using magnetic fluids to simulate convection in a central force field in the laboratory
magnetic fluids convection central force field
2009/11/11
Large-scale convection in planetary or stellar interiors plays a significant role but it is difficult to reproduce the central force field of those systems in experimental studies. A technique to appr...
Phase synchronization of slip in laboratory slider system
Phase synchronization of slip laboratory slider system
2009/11/9
In the present study the character of slip regimes in laboratory spring-slider system under weak external periodical forcing has been investigated. We report the experimental evidence of phase synchro...
Rupture modes in laboratory earthquakes: Effect of fault prestress and nucleation conditions
Rupture modes in laboratory earthquakes fault prestress nucleation conditions
2014/4/8
Seismic inversions show that earthquake risetimes may be much shorter than the overall rupture duration, indicating that earthquakes may propagate as self‐healing,pulse‐like ruptures. Several mechanis...
