Depth-Varying Constitutive Properties Observed in an Isothermal Glacier
[1] Detailed three-dimensional in-situ measurements of deformation at depth are used to examine the rheology of a 6 10 m block of temperate glacier ice. Assuming that the viscosity of this ice is primarily dependent on stress, the relationship between inferred stress and measurements of strain-rate above 115 m depth suggest a constitutive relationship with a stress exponent n 1. Deformation bel...
متن کاملAWM 4 - an isothermal cluster observed with XMM - Newton
We present analysis of an XMM-Newton observation of the poor cluster AWM 4. The cluster is relaxed and its X-ray halo is regular with no apparent substructure. Azimuthally averaged radial spectral profiles suggest that the cluster is isothermal to a radius of at least 160 kpc, with no evidence of a central cooling region. Spectral mapping shows some significant temperature and abundance substru...
متن کاملDepth-varying rupture properties of subduction zone megathrust faults
[1] Subduction zone plate boundary megathrust faults accommodate relative plate motions with spatially varying sliding behavior. The 2004 Sumatra-Andaman (Mw 9.2), 2010 Chile (Mw 8.8), and 2011 Tohoku (Mw 9.0) great earthquakes had similar depth variations in seismic wave radiation across their wide rupture zones – coherent teleseismic short-period radiation preferentially emanated from the dee...
متن کاملIntermediate-depth icequakes and harmonic tremor in an Alpine glacier (glacier d 'Argentiere,France): evidence for hydraulic fracturing
We detected several thousand deep englacial icequakes on Glacier d’Argentière (Mont-Blanc Massif) between 30 March and 3 May 2012. These events have been classified in eight clusters. Inside each cluster, the waveforms are similar for P-waves and S-waves, although the time delay between the P-waves and S-waves vary by up to 0.03 s, indicating an extended source area. Although these events were ...
متن کاملIndentation of an elastic half space with material properties varying with depth.
We consider the effect of an elastic modulus that decreases with depth on the load-displacement relation for indentation of a graded half space by a rigid indenter. A closed-form approximation incorporating features of the plate on an elastic substrate and the Hertzian contact theory is compared with finite element results for the case of a uniform stiff layer on a homogeneous substrate. Some g...
