The youngest tectonic structures in Tibet are a series of grabens trending approximately north-south. However, the grabens in central Tibet are less prominent than those in southern Tibet, which suggests that there is spatial variability in deformation mechanisms. The Chem Co half-graben is situated in the westernmost segment of central Tibet and i...

Quantifying today's topography can provide insights into landscape evolution and its controls, since present topography represents a cumulative expression of past and present surface processes. The Ulsan Fault Zone (UFZ) is an active fault zone on the southeastern Korean Peninsula that was reactivated as a reverse fault around 5 Ma. The UFZ strikes...

Paleoseismological research for a slowly deforming intraplate fault can provide essential information for understanding not only the spatiotemporal characteristics of past earthquakes but also seismic behavior in the case of long recurrence intervals. To reveal the paleoseismological properties and faulting processes of the intraplate fault, the Ge...

Advanced technologies such as light detection and ranging (LiDAR) and unmanned aerial vehicles (UAVs) have revolutionized the detection of subtle surface deformation and the generation of high-resolution digital elevation models, overcoming the challenges posed by low tectonic activity and climatic surface erosion on fault-generated landscapes. Thi...

Quantifying present topography can provide insights into landscape evolution and its controls, as the present topography is a cumulative expression of the types, distributions, and intensities of past and present processes. The Ulsan Fault Zone (UFZ) is an active fault zone on the southeastern Korean Peninsula that has been reactivated as a reverse...

Integration of geological and geophysical data is essential to elucidate the configuration and geometry of surface and subsurface structures, as well as their long-term evolution. The NNW–SSE-striking incised valley and parallel mountain range in the southeastern margin of the Korean Peninsula, extending 50 km from Gyeongju to Ulsan cities, are tog...

The origin of relatively high topography in intraplate settings is elusive. The St. Francois Mountains, a tectonically inactive region with high relief, a Mesoproterozoic granite and rhyolite core, and Paleozoic sedimentary flanks, provide insights into the evolution of intraplate landscapes. We determined 14 in situ10Be exposure ages, 23 10Be catc...

Passive continental margins can show anomalously high topography and exhibit a discrete steep escarpment, divide, and gentle slope from the exterior to the interior of the margin. Compared with active (i.e. convergent and strike-slip) tectonic regions, the processes and rates of change of high-altitude landscapes driven by tectonics and/or climate...

Quaternary fault research has mainly been done with the focus of the outcrop and trench to identify the sense and displacement of the fault. Because the result from the outcrop and trench is obtained from exposed sections, the interpretation of fault information is likely to be overestimated or underestimated. Quaternary faulting affected the curre...

Forebergs are landforms characterized by low, elongated ridges or hills rising above the surrounding alluvial fans or floodplains, and are typically formed by folding associated with thrust faulting. Forebergs in the Gobi-Altay range, south-central Mongolia, have developed in the forelands of mountains transpressionally uplifted in restraining bend...

Deriving paleoseismological fault parameters of active faults is essential for earthquake disaster provision. The purpose of this study is to document the fault characteristics of Wonwonsa fault, which was recently reported in the 2nd fault outcrop on the eastern side of the Ulsan fault, and to provide fault parameters, such as the timing of activi...

Evolution of Colorado River has been a center of debate over the last decades among the multiple disciplines of Geo-society, in particular relation to the timing and mode of initiation of Grand Canyon and the uplift of Colorado Plateau. One of the key resources for the debate is a series of alluviums including Bullhead, Santa Fe Railroad, Bat Cave,...

Foreberg' is a low, elongated ridge or hill with low relief parallel to the main mountain range, rising above the surrounding alluvial fans and floodplains, and is typically formed by thrusting (Florensov and Solonenko, 1963; Bayasgalan et al., 1999; Owen et al., 1999). When hanging wall moves toward the foreland, the vertical displacement of the o...

The Taebaek Mountain Range (TBR) initially formed via extension of a back-arc basin in the East Sea during the early-Miocene (ca. ~22 Ma) and exemplifies a typical escarpment on a passive continental margin. The TBR acts as a major watershed and divide across which topography changes fromgentle western side slopes to steep eastern slopes. Compared...

LiDAR, digital topographic map, aerial photo-based DEMs were generated for the area of 27 square kilometers including Byuckgae and Dangu fault site reported from the central segment of Yangsan fault, SE Korean Peninsula. We compared the characteristics of lineament detection and the results of lineament extraction based on the type of DEMs. The gen...

The construction of a high-resolution Digital Elevation Model (DEM) with cell size smaller than 1 m and the development of GIS technology enabled quantitative topographic classification. This study carried out the landform classification using the geomorphons, which categorize the terrain according to its morphological characteristics. The study ar...

The Yangsan Fault is one of the main fault systems in the Korean peninsula. It can be divided into three segments (northern, central, and southern) by its paleoseismic and structural geologic properties. Based on the geomorphic features of the northern segment, which includes the Yugye Fault, we identified deflected streams as a geomorphic marker o...

The concentration of cosmogenic 10Be in riverine sediments has been widely used as a proxy for catchment-wide denudation rate (CWDR). One of the key assumptions of this approach is that sediments originating from sub-basins with different erosional histories are well mixed. A tragic debris flow occurred in the Seti River watershed, central Nepal, o...

The Ozark Mountains, Missouri and Arkansas, pose a major geologic and geomorphic anomaly. They form a topographically high, structurally uplifted “block” that exposes buoyant (?) mid-Proterozoic granite-rhyolite basement rocks in the North American mid-continent. The Ste. Genevieve fault bounds the Ozarks on its steepest and structurally highest no...
