Earthquakes are a high-risk natural phenomenon in Indonesia, which is between three tectonic plates: the Eurasian, Pacific, and Indo–Australian plates. This study examines response of bored piles with asymmetrical pile cap Auditorium Building Brawijaya University to seismic loads, still rare conduct this research. assessed based on 3D finite element-numerical approach, where lateral resistance ...
[1] We show evidence of very recent ( 25–40 Myr) geologic activity on the eastern flank of Olympus Mons volcano that includes a suite of fluvial (channel networks), volcanic (emplacement of lava flows and dikes), and tectonic (wrinkle ridges and troughs) processes. The combination and youth of these features confirms the importance of geological activity continuing to the present on Mars. Citat...
Arc continent collision is one of the most fundamental tectonic processes for the formation of new land, and the preservation on land of fragments of oceanic lithosphere (ophiolites). However, the tectonic evolution of arc continent collision is commonly over-simplified in everything from introductory textbooks to complex tectonic models. Major unresolved issues include the response of the fore...
Topographically complex regions on land and in the oceans feature hotspots of biodiversity that reflect geological influences on ecological and evolutionary processes. Over geologic time, topographic diversity gradients wax and wane over millions of years, tracking tectonic or climatic history. Topographic diversity gradients from the present day and the past can result from the generation of s...
The slightly submerged Bering Shelf-Chukchi Sea region comprises over 50% of the total U.S. continental shelf area and forms a broad isthmus of continental crust connecting the North American and Asian continents (Fig. 1). Although harsh climate and remoteness make this a difficult area to work in, there has been much interest in the stratigraphic framework and evolution of sedimentary basins o...
[1] We show that the two-dimensional coherence between topography and Bouguer gravity is anisotropic throughout most of the Canadian Shield, excepted Hudson Bay Basin. We interpret the axis of maximum coherence as the direction where the lithosphere is weakest. In the southeastern Shield and the Appalachians, the azimuthally averaged coherence cannot be fitted by the thin elastic plate model. I...
The geocentric realm of tectonics changed with the dawn of robotic exploration of the other bodies of the solar system. A diverse assortment of tectonic landforms has been revealed, some familiar and some with no analogues to terrestrial structural features. In this chapter, we briefly introduce some of the major topics in the book. The chapters review what is known about the tectonics on Mercu...
– We report on experimental and theoretical results on the dynamical behavior of propagating solitary relaxations in a model system for earthquake-like dynamics. In the experiments, a continuous elastic medium is sheared at very slow rate in between two coaxial cylinders. Solitary propagating relaxations travel at speeds that are proportional to the driving speed, though ∼ 10 times faster, and ...
Tectonic geomorphology is part of Earth Sciences, which deal with study of the interaction of tectonic and geomorphology. In other words it studies the effective tectonic processes in forming and changing the landforms. Geomorphic and morphometric indicators are suitable tools to the morphotectonic analysis for different areas. These indicators are used as the base tool to identify and recognit...
