Several processes may produce global tectonic patterns on the surface of a planetary body. The stresses associated with distortions of biaxial figures due to despinning or reorientation were first calculated by Vening Meinesz [Vening Meinesz, F.A., 1947. Trans. Am. Geophys. Union 28 (1), 1–23]. We adopt a mathematically equivalent, but physically more meaningful treatment for distortions associ...

In order to assess the age relations between astra/novae (features with extensive radial fracture-graben systems) and their surroundings, and to determine the duration of their activity, we undertook a photogeologic analysis of Magellan images of 78 astra, 49 dark-parabola craters and 114 clear-halo craters. For seven of these 78 astra it was found that the astrum-forming faulting started befor...

Abstract Rift-basins are the shallow effects of lithosphere-scale extensional processes often producing polyphase faulting. Their sedimentary evolution depends on mutual interplay between tectonics, climate, and eustasy. Estimating role each factor is generally a challenging issue. This paper focused tectono-sedimentary Neogene Siena-Radicofani Basin, structural depression located in inner Nort...

The origin of the Aburrá Valley (AV) is proposed as a set coalescent tectonic subbasins located along northern portion Central Cordillera Colombia, Northern Andes Colombia. Itagüí, Medellín, Bello, and Barbosa have developed between Romeral Shear Zone (RSZ) Antioqueño Batholith starting in Late Cenozoic. aim this study to contribute understanding AV neotectonic framework using anisotropy magnet...

The Mw 6.2 (Mj 6.8) Nagano (Japan) earthquake of 22 November 2014 produced a 9.3-km long surface rupture zone with a thrust-dominated displacement of up to 1.5 m, which duplicated the pre-existing Kamishiro Fault along the Itoigawa-Shizuoka Tectonic Line (ISTL), the plate-boundary between the Eurasian and North American plates, northern Nagano Prefecture, central Japan. To characterize the acti...

Paleoseismological study of geologic features thought to result from Quaternary tectonic faulting can characterize the frequencies and sizes of large prehistoric and historical earthquakes, thereby improving the accuracy and precision of seismichazard assessments. Greater accuracy and precision can reduce the likelihood of both underprotection and unnecessary design and construction costs. Publ...
