[1] Lobate scarps on Mercury are the surface expression of thrust faults and are generally thought to be the result of global contraction. Our analysis indicates that these thrust faults are not uniformly distributed and exhibit non-random patterns on the imaged hemisphere. The greatest area normalized cumulative length of the faults occurs in the southern hemisphere, below 50 S. The thrust fau...

In distributed wireless sensing applications such as unattended ground sensor systems, remote planetary exploration, and condition based maintenance, where the deployment site is remote and/or the scale of the network is large, individual emplacement and configuration of the sensor nodes is difficult. Hence network self-assembly and continuous network self-organization during the lifetime of th...

M. P. Searle's recent paper in the Journal of Structural Geology (Searle 1986) included a major departure from published structural interpretations of the Ladakh Himalaya. The geologic history of Ladakh is a vital key to understanding the timing and sequence of events during the Himalayan orogeny. Ophiolitic rocks and island arc volcanics along the Indus Suture zone (Frank et al. 1977, and many...

• The thickness of terrestrial long runout landslides scales with the wavelength longitudinal ridges. Basal ice is not a necessary condition for formation ridges in landslides. Internal structures observed may point to vibration-assisted mechanism during landslide emplacement. are associated stress fluctuation, which qualitatively agree acoustic fluidization. Longitudinal spanning over 5 order ...

Introduction: Impact craters are a dominant geological landform on Mars, the most Earth-like planet in the Solar System. The martian impact cratering record is more diverse than for Earth and the other terrestrial planets [e.g., 1]. Of particular interest is the presence of multiple layers of lobate or fluidized proximal ejecta deposits surrounding martian impact craters. These are collectively...

[1] Moon Mineralogy Mapper (M) image and spectral reflectance data are combined to analyze mare basalt units in and adjacent to the Orientale multiring impact basin. Models are assessed for the relationships between basin formation and mare basalt emplacement. Mare basalt emplacement on the western nearside limb began prior to the Orientale event as evidenced by the presence of cryptomaria. The...

[1] Small volcanic edifices, shields with a diameter less than about 20 km, are common and sometimes very abundant features on the plains of Venus. Typically, they form tight or loose clusters of features known as shield fields. Small shields are interpreted to be formed due to small-scale eruptions through numerous and distinct sources, a mode of formation apparently significantly different fr...

[1] Several zones of graben (Memnonia, Sirenum, Icaria, Thaumasia, and Claritas Fossae) extend radially away from the Tharsis rise in the southern hemisphere of Mars for distances of up to 3000–4000 km. These graben systems are commonly interpreted to be related to regional tectonic deformation of the Tharsis rise associated with either upwelling or loading. We explore the possibility that thes...
