Geological Journal, EarlyView.New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Seismic imaging of crustal structure at mid-ocean ridges: a three-dimensional approach [PDF]
, 2001 Over recent years geological, geochemical and geophysical surveys of mid-ocean ridges have revealed a significant degree of along-axis variability not only in seabed morphology, but also in crustal structure, particularly Numerous geophysical surveys of ...

Sustainable Development, EarlyView.ABSTRACT Risk management has evolved to analyze risks in a systemic way, integrating local knowledge with the abstract concept of resilience, which is now an imperative for vulnerable and exposed communities. However, existing decision‐support tools are mainly focused on technical‐functional aspects and, although based on rigorous and scientific ...
