Intermediate-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 کاملBasal icequakes recorded beneath an Alpine glacier (Glacier d 'Argentiere,MontBlanc, France): evidence for stick-slip motion
While basal icequakes associated with glacier motion have been detected under Antarctica for several decades, there remains very little evidence of stick-slip motion for Alpine glaciers. Here we analyzed 2357 basal icequakes that were recorded at Glacier d’Argentière (Mont-Blanc Massif) between February and November of 2012, and that are likely to be associated with basal sliding. These events ...

A hanging glacier at the east face of Weisshorn broke off in 2005. We were able to monitor and measure surface motion and icequake activity for 21 days up to three days prior to the break-off. Results are presented from the analysis of seismic waves generated by the glacier during the rupture maturation process. Three types of precursory signals of the imminent catastrophic rupture were identif...
متن کاملFrom Surface Roughness to Surface Displacements
This paper presents an extension to a measurement system to capture bidirectional refEectance distribution function (BRDF) values and texture maps out of images. The extension will enable the measurement of reflection effects due to surface roughness and additionally extracts a map representing local surface displacements. Different lighting conditions where used to discriminate between surface...
متن کاملA New Guidance Method for Surface to Surface Ballistic Missiles without Mandatory Engine Cut-Off
In this paper, a new guidance method for surface to surface ballistic missiles without mandatory engine cut-off will be presented. The complexity of solid fuel engine cut-off demands a comprehensive method for guiding these missiles. In the method presented in this paper, a certain guidance law is applied such that by transmitting appropriate commands to the control system, by changing the miss...
