Surface movement and deformation with fault differ significantly from that without fault. To explore the mechanism of abnormal surface subsidence induced by instability, mechanical model for slip soil cantilever were separately established when mining in hanging wall footwall. Moreover, based on numerical similarity simulation experiment, difficulty instability was compared analysed. The result...

Abstract Tectonically controlled topography influences deep-water sedimentary systems. Using 3-D seismic reflection data from the Levant Basin, eastern Mediterranean Sea, we investigate spatial and temporal evolution of bedforms on a fan cut by an active normal fault. In footwall, comprises cyclic steps antidunes along its axial external portions, respectively, which interpret to result variati...

Thrust fault earthquakes are studied in a laboratory earthquake setup previously used to investigate analog strike-slip seismic events. Dynamic mode II ruptures are generated along preexisting faults in an analog material, Homalite H-100, and their interaction with the free surface is studied for both sub-Rayleigh and supershear rupture speeds. High-speed digital photography and laser velocimet...

Gold mineralisation is the result of physico-chemical and thermal processes of the earth’s interior. We may view a geological process of gold mineralization as a stochastic process Z(x): xD, where D may be considered as a mineral deposit. In the case of gold mineralization, samples drawn at regular intervals may be considered as following a discrete stochastic process. The point of interest is...

Forty-six mining-induced seismic events with moment magnitude between -1.2 and 2.1 that possibly caused damage were studied. The events occurred between 2008 and 2013 at mining level 850–1350 m in the Kiirunavaara Mine (Sweden). Hypocenter locations were refined using from 6 to 130 sensors at distances of up to 1400 m. The source parameters of the events were re-estimated using spectral analysi...

Basement highs form one of many potential sediment source areas during the evolution continental rifts and rifted margins add to topographic complexity typical active rifts. Footwall basement acting as a area sedimentary systems in hangingwall major faults have been documented worldwide. However, back-tilted footwall dip slopes such received comparatively little attention. Here, we investigate ...

Abstract The seismic hazard posed by submarine faults and the capacity of earthquakes to trigger mass wasting are poorly understood because we lack detailed characterizations coseismic ruptures at seafloor. Here, present comprehensive mapping a seafloor rupture caused 2004 M w 6.3 Les Saintes earthquake on Roseau normal fault in Lesser Antilles. We report visual characteristics, displacement pr...

Abstract Oceanic core complexes (OCCs) and detachment faults play a key role in crustal accretion at slow ultraslow spreading centers. We investigated the effect of different magma supply three OCCs Southwest Indian Ridge using high-resolution deep-sea bathymetric magnetic data. The average equivalent thickness extrusive basalt deduced from anomalies, proxy for supply, decreases west to east, Y...
