Composite rock slope kinematics at the current Randa instability, Switzerland, based on remote sensing and numerical modeling

“…(4) Holocene multiphase rock-slope failure occurred and moved into the ice-free valley, forming both the ridge deposits and the continuous rock-avalanche deposit. Such a multiphase event might be composed of several sub-events and might have lasted over a time period of several days or weeks, similarly to the Randa rockslide (Sartori et al, 2003;Willenberg et al, 2008;Gischig et al, 2011). The complex interaction and the smaller volumes of the sub-events might develop atypical rockslide deposits such as a steep talus cone with a relatively short runout length according to its total volume.…”

“…The author proposes a new theory and method, called the phase-separation analysis method, of remote sensing images for regional tectonic stress fields and deformation fields based on the features of remote sensing multispectral images and properties of the genetic relationship between major transverse tensional joints and the related folds and faults (Kounov, Andreoli, and Mattila, 2011;Liu et al, 2005). This method was used in complex structural deformation areas and has achieved remarkable results (Babaahmadi et al, 2010;Gischig et al, 1996).…”

Yang, X.; Yang, W.; Liu, H.; Qin, Z., and Wu, X., 2015. Combining quantitation of remote sensing information of local structures-bearing oil/gas underground and calculation of structural deformation and stress field.Marine oil and gas resources are very rich in China, especially in coastal zone and shallow sea continental shelf, but the exploration technology is relatively underdeveloped. The tectonic stress field is crucial to the study of tectonics, engineering, marine geology, seismology and the exploration of marine resources. In the exploration of marine resources, it is often necessary to study the mechanics and deformations of the rock in the oceanic crust. An iso-elevation line map of the fold's structural layer is a basic way to indicate the features and shapes of the fold, which is more important -especially in the field of exploratory marine petroleum engineering. To draw this map, though, requires a great deal of data, for structural profiles and drilling. It is very difficult to obtain these data, especially in mountainous regions or areas where mineral exploration has recently begun. This greatly limits the progress of marine exploratory engineering. In this paper, the author proposes a new theory and method for calculating the structural stress field using the composite quantitative data of remote sensing information on circular structures and related linear structures, in order to approximate the iso-elevation line map of local structures on the basis of the phase-separation analysis of remote sensing information field and the theory of elastic mechanics. The theory and method have been practically applied in many tested areas, and its effects are remarkable. ADDITIONAL INDEX WORDS:The exploration of marine resources, combining quantitation of remote sensing information, circular/ring structures, linear structures, structural stress field, quantitative analysis.
