Earthquakes are notoriously hard to predict, and so too are the usually less-severe aftershocks that often follow a major seismic event.
Experiments call origin of Earth's iron into question
Experiments call origin Earth's iron
2017/3/14
New research from The University of Texas at Austin reveals that the Earth’s unique iron composition isn’t linked to the formation of the planet’s core, calling into question a prevailing theory about...
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...
Determination of volatiles in volcanic rocks and minerals with a Directly Coupled Evolved Gas Analyzing System (DEGAS) -Part I: Interpretation of degassing profiles (DEGAS-profiles) of minerals and rocks on the basis of melting experiments

2015/9/10
Volatile components in magma strongly influence many physical properties of melts and minerals. The temperature
resolved degassing analysis of volcanic crystalline and vitreous rocks gives detailed i...
Transport processes at quartz–water interfaces: constraints from hydrothermal grooving experiments
Hydrothermal annealing experiment quartzite fluid pressure the topological structure
2015/1/6
We performed hydrothermal annealing experiments on quartzite samples at temperatures of 392 to 568 °C and fluid pressures of 63 to 399 MPa for up to 120 h, during which hydrothermal grooves developed ...
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.
Enhanced runout and erosion by overland flow at low pressure and sub-freezing conditions: Experiments and application to Mars
Mars, Surface Geological processes Experimental techniques
2014/4/8
We present the results of laboratory experiments to study the sediment transport and erosional capacity of water at current martian temperature and pressure. We have performed laboratory simulation ex...
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...
On aspects of the measurement of non-linear turbulence processes using the cluster wave experiments
measurement of non-linear turbulence processes cluster wave experiments
2009/11/16
The ESA/NASA Cluster mission has four identical satellites and is due for launch at the end of 1995. It will provide a unique opportunity to study medium scale processes in the region from inside the ...
Low-frequency variability in idealised GCM experiments with circumpolar and localised storm tracks
Low-frequency variability idealised GCM experiments circumpolar localised storm tracks
2009/11/12
Idealised global circulation model simulations with circumpolar and localised (one and two) storm tracks are re-analysed to determine scaling, intermittency and phase-space structures. In a hundred ye...
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...
