Geochemical features and effects on deep-seated fluids during the May-June 2012 southern Po Valley seismic sequence
Fluids Geochemistry Faults Temporal changes
2015/8/26
A periodic sampling of the groundwaters and dissolved and free gases in selected deep wells located in the area affected by the May-June 2012 southern Po Valley seismic sequence has provided insight i...
Velocity structure and the role of fluids in the West Bohemia Seismic Zone
Double difference fault three-dimensional structure seismic belt regional earthquakes earthquake focal mechanism
2015/1/6
In this study, we apply the double-difference tomography to investigate the detailed 3-D structure within and around the Novy Kostel Seismic Zone, an area in the Czech Republic known for frequent occu...
The fate of fluids released from subducting slab in northern Cascadia
fluids released subducting slab northern Cascadia
2015/1/4
Large amounts of water carried down in subduction zones are driven upward into the overlying forearc upper mantle and crust as increasing temperatures and pressure dehydrate the subducting crust. Thro...
Bifurcations and instabilities in rotating two-layer fluids:I.f-plane
Bifurcations instabilities two-layer fluids I.f-plane
2009/11/12
In this paper, we show that the behaviour of weakly nonlinear waves in a 2-layer model of baroclinic instability on an f-plane with varying viscosity is determined by a single, degenerate codimension ...
Bifurcations and instabilities in rotating,two-layer fluids:II. β-plane
Bifurcations instabilities two-layer fluids β-plane
2009/11/12
In this paper, we show that the behavior of weakly nonlinear waves in a 2-layer model of baroclinic instability on a b-plane with varying viscosity is determined by a single, degenerate codimension th...
Viscous heating in fluids with temperature-dependent viscosity:implications for magma flows
Viscous heating in fluids temperature-dependent viscosity magma flows
2009/11/12
Viscous heating plays an important role in the dynamics of fluids with strongly temperature-dependent viscosity because of the coupling between the energy and momentum equations. The heat generated by...
A continuum theory is developed for a geophysical fluid consisting of two species. Balance laws are given for the individual components of the mixture, modeled as micropolar viscous fluids. The contin...
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...
Turbulence in nearly incompressible fluids:density spectrum,flows,correlations and implication to the interstellar medium
nearly incompressible fluids density spectrum flows correlations implication interstellar medium
2009/11/9
Interstellar scintillation and angular radio wave broadening measurements show that interstellar and solar wind (electron) density fluctuations exhibit a Kolmogorov-like k-5/3 power spectrum extending...
Nonlinear dynamics of turbulent waves in fluids and plasmas
Nonlinear dynamics turbulent waves fluids plasmas
2009/11/9
In a model drift wave system that is interesting both in fluids and plasmas, we find that an embedded moving saddle point plays an important role at the onset of turbulence. Here the saddle point is a...
Penetrative convection in stratified fluids:velocity and temperature measurements
Penetrative convection stratified fluids velocity and temperature measurements
2009/11/9
The flux through the interface between a mixing layer and a stable layer plays a fundamental role in characterizing and forecasting the quality of water in stratified lakes and in the oceans, and the ...
The Role of Crustal Fluids in Strike-slip Tectonics: New Insights from Magnetotelluric Studies
crustal fluids magnetotelluric strike-slip tectonics transform plate boundaries crustal deformation
2009/7/8
The presence of fluids in the Earth's crust can dramatically change the rheology and may control a wide range of tectonic processes, especially in regions characterized by strike-slip deformation. Flu...
