Active Tectonics of the Eastern and Southern Alps ‐ Crustal Response to Deep Processes? A Review
Abstract Owing to the low N‐S convergence rates between Adria and Europe, crustal deformation rates in the Alps and its forelands are low. Active tectonics are, therefore, difficult to study, especially as non‐tectonic landscape forming processes can erase or modify the tectonic surface imprint. Large‐scale and dense seismological data recently offered

Abstract Fjords are globally significant sedimentary archives that record the relationship between glacial, tectonic, and marine processes. Fiordland, on the southwest coast of New Zealand, hosts one of the most extensive temperate fjord provinces in the Southern Hemisphere, yet its postglacial evolution has remained poorly constrained.

Abstract The timing, stratigraphic development, and mechanisms of late Paleogene loess deposition remain poorly understood, yet they are critical to understanding how tectonics, fluvial reworking, and eolian transport interacted during a key interval of western North American landscape evolution.

The Western Basin of the North Gulf of Evia rift is a complex, normal fault‐controlled basin. In this study we develop the first pre‐Holocene syn‐kinematic age model here and apply it to better understand rift evolution, basin control, and timing of fault migration in the active rift.

ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Extreme Events Reshape Flood Hazards Through Sediment‐Induced Channel Change in Southern Taiwan
Abstract Extreme precipitation events can cause long‐lasting changes to river systems, altering flood hazards beyond the initial disaster. We investigate how Typhoon Morakot (2009) impacted flood inundation patterns across four river catchments in southern Taiwan.

Abstract Chronological studies of glacial sediments from the Shishapangma and Yarlung Tsangpo River valley indicate that Quaternary glaciation on the southern Tibetan Plateau commenced at ∼0.75–0.83 Ma. However, the oldest glacial deposits in the northern plateau are dated to only ∼0.46 Ma, markedly later than the Middle Pleistocene glacial ...

2008年汶川MS8.0地震现场的震害调查资料显示,河流阶地地形对建筑物震害分布的影响规律表现为:阶地前缘冲洪积层较厚区域的建筑物遭受了严重的破坏,而阶地后缘坡积层较薄区域受损则相对较轻,总体上呈现出前缘震害显著大于后缘的特征。为研究该震害特征的机制,利用有限差分软件FLAC3D构建三维阶地模型,模拟分析了脉冲荷载作用下阶地模型的地震动响应。结果表明:各级阶地前缘的地震动水平均显著高于后缘,同时随着上覆土层的增厚,峰值加速度、相对持时值、反应谱平台值以及放大系数均呈现上升趋势;随着阶地级数的减小 ...

Gentle Slopes and Fluvial Terraces around Mt. Shokanbetsudake, Hokkaido
This paper discusses the paleoenvironment of eastern slopes of Mt. Shokanbetsudake, Hokkaido, on the basis of evidences of gentle slopes and fluvial terraces.The fluvial terraces are classified into five surfaces (terrace I to V in descending order) and the gentle slopes into two surfaces (gentle slope I and II). In most case, gentle slope I and gentle
