[1] We report on laboratory experiments in which stick-slipping shear surfaces are subject to transient stressing to simulate earthquake triggering by seismic waves. Granular layers and bare granite surfaces were sheared in a servo-controlled deformation apparatus in double-direct shear. The seismic waves from an earthquake and tectonic load were simulated by superimposing a loading rate sinuso...

Quiescent faults may be capable of creating catastrophic earthquakes in locations with moderate and/or low seismic activity, such as Egypt. This study combines structural, remote sensing (RS), geophysical, and activity data to examine analyze the relationship between tectonic structures seismotectonic In a new seismo-lineaments map Egypt, lineaments Egyptian mainland were delineated classified....

Abstract In this paper, a new way of characterizing the mining-driven complex geological deformations is presented by utilizing continuous real-time microseismic (MS) data acquired through passive seismological monitoring. The was processed, and source parameters were computed encompassing over 60,000 MS events. correlation between events regional stratigraphy reveals that Upper Middle Xishanya...

Comparison of the distributions of Martian and lunar crater diameters indicates that the visible surface of Mars is 2.2 to 3 x 10(9) years old. This result implies that in the early history of Mars large-scale subaerial erosion occurred. Of 69 Martian craters with diameters greater than 10 kilometers, 13 percent have central peaks. This compares favorably with the frequency (11.7 percent) of ce...

This paper presents a study of the structural lineaments of the Pantanal extracted visually from satellite images (CBERS-2B satellite, Wide Field Imager sensor, a free image available in INTERNET) and a comparison with the structural lineaments of Precambrian and Paleozoic rocks surrounding the Cenozoic Pantanal Basin. Using a free software for satellite image analysis, the photointerpretation ...

in recent years, underactuated nonlinear dynamic systems trajectory tracking, such as space robots and manipulators with structural flexibility, has become a major field of interest due to the complexity and high computational load of these systems. hierarchical sliding mode control has been investigated recently for these systems; however, the instability phenomena will possibly occur, especia...

Seismic attribute analysis is important in subsurface data interpretation, such as seismic which could involve stratigraphic and structural interpretation. This interpretation often hampered by resolution and, sometimes, human inability to identify a subtle feature on the seismic. These factors have frequently led poor of geologic features. Thus, an integral approach studying patterns hydrocarb...

Receiver Operator Characteristic (ROC) curves are commonly applied as metrics for quantifying the performance of binary fault detection systems. An ROC curve provides a visual representation of a detection system’s True Positive Rate versus False Positive Rate sensitivity as the detection threshold is varied. The area under the curve provides a measure of fault detection performance independent...
