We present new methods for physical interpretation and mathematical treatment of the imaging contrast observed in thermal images rocky upper scarp Poggio Baldi landslide (Italy), which is part a natural laboratory. Exemplar have been acquired with high-performance camera at distance around 500 m, geometry where reflection expected to dominate over emission. The digital pixel intensities therefo...

Abstract Four previously unrecognized neotectonic fault scarps in southwest Namibia are described. These relatively straight, simple but segmented structures 16–80 km long and have measured vertical separations of 0.7–10.2 m. We estimate that each is capable producing earthquakes M w 6.4 or greater, indicating large may occur despite limited cumulative displacement. There strong evidence some t...

Although the origin and composition of many units are obscure or controversial, their interpretations are based on objective descriptions of morphologic characteristics visible on Viking photomosaics and images. LOWLAND TERRAIN MATERIALS Consist of all plains-forming units between the highland-lowland boundary scarp and the north edge of the map area, exclusive of materials of the western volca...

Introduction: Recent detections of phyllosilicate (clay) minerals in ancient terrains [1-3] have revolutionized our understanding of early hydrothermal activity on Mars. The spectral signatures of phyllosili-cates are seen exclusively in Noachian-aged outcrops and not in Hesperian or Amazonian materials [1-3]. Phyllosilicates are inferred to have been widely em-placed during a period of time (t...

The volume of a submarine landslide is likely to be amplified by shear band propagation along basal surface or spreading failure extension in the sliding layer. Although mechanism translational landslides has been understood using interpretation propagation, assessment limits extension, either through retrogressive spreading, remains challenge due diversity post mechanisms. paper aims explore a...
