This paper aims to provide an insight into the urban governance of four medium-sized Haitian cities hit by the earthquake of 2010, bearing in mind two affirmations of J. Pierre on urban governance; namely, that it is the better analytical model for the con ...
Introduction to geothermal energy: what is geothermal energy, main applications (heat pumping, direct use, electricity production and cogeneration), geothermal resources, geothermal power plants. ...
Fluid-rock interactions can control earthquake nucleation and the evolution of earthquake sequences. Experimental studies of fault frictional properties in the presence of fluid can provide unique insights into these interactions. We report the first resul ...
Oil and gas production from unconventional reservoirs (i.e. tight) now accounts for about half of the total US hydrocarbon production from essentially zero ten years ago. Such a drastic increase in production from unconventional resources was made possible ...
Using a spectral resolution of the elastodynamic boundary integral equations, this poster is presenting the effect of tougher heterogeneities along a planar fracture plane. A centered crack propagating along a 1-D heterogeneous interface under mixed-mode l ...
This study presents a dynamic-induced direct-shear model to investigate the dynamic triggering of frictional slip on simulated granular gouges. An incident P-wave is generated as a shear load and a normal stress is constantly applied on the gouge layer. Th ...
An experimental investigation is conducted to study the quasi-static and dynamic fracture behaviour of sedimentary, igneous and metamorphic rocks. The notched semi-circular bending method has been employed to determine fracture parameters over a wide range ...
Geologic CO2 sequestration is considered to be the most promising technique to reduce the concentration of greenhouse gases in the atmosphere. Among all the storage options, deep saline aquifers have the greatest potential and due to their worldwide occurr ...
We performed 31 friction experiments on glassy basalts (GB) and glass-free basalts (GFB) at slip rates up to 6.5 m s-1 and normal stress up to 40 MPa (seismic conditions). Frictional weakening was associated to bulk frictional melting and lubrication. The ...
The spatiotemporal evolution of stress state is analyzed during the 2009-2010 Slow Slip Event (SSE) of Guerrero, Mexico, based on the kinematic inversion results and using an integral expression for stress changes. A linear slip weakening behavior is gener ...
