Palaeoseismicity recorded in soft-sediment deformation structures within a 166-m-long drill core from Diexi Palaeolake, eastern Tibetan Plateau Open
Soft-sediment deformation structures (SSDS) in water-saturated, unconsolidated sediments are the product of various causes and provide a valuable record of environmental and geological perturbations. We report a record of SSDS preserved in…

A late Pleistocene glacial maximum during MIS 3 in the Chersky Mountains, central northeast Siberia Open
The glacial history of northeast Siberia is poorly understood compared with other high-latitude regions. Using 10 Be and 26 Al exposure dating together with remote sensing, we have investigated the glacial history of a remote, formerly gla…

Deep learning can predict global earthquake-triggered landslides Open
Earthquake-triggered (coseismic) landsliding is among the most lethal of disasters, and rapid response is crucial to prevent cascading hazards that further threaten lives and infrastructure. Current prediction approaches are limited by ove…

Unraveling burial histories with CosmoChron Open
Cosmogenic nuclides measured in depth-profiles are a valuable tool for reconstructing the depositional and erosional history of sedimentary sequences. The burial ages of these sequences can be determined by measuring cosmogenic nuclide pai…

An advance of the Eurasian Ice Sheet to the Central European Uplands preceded MIS Open
Records of ice-rafted detritus (IRD) from the global oceans indicate the expansion of large Northern Hemisphere ice sheets prior to the Plio–Pleistocene transition. Yet, the geometry of these early ice sheets remains unclear due to l…

Comprehensive temporal and spatial analysis of Early Pleistocene drainage patterns on the Swiss Alpine foreland Open
Deckenschotter are glaciofluvial gravels that cap isolated bedrock plateaus and are largely disconnected from today's local drainage. They were deposited when glaciers from the Alps were first extensive enough to reach the northern Swiss f…

Terrace formation linked to outburst floods at the Diexi palaeo-landslide dam, upper Minjiang River, eastern Tibetan Plateau Open
River terraces are frequently investigated with the aim of extracting information regarding tectonic or climate forcing on the evolution of landscapes. Terraces formed following the blockage of valleys by large-scale landsliding have recei…

Surface Uplift Due To Time‐Varying Elastic Thickness in Continental Interiors Open
If, as previously hypothesized, the effective elastic response of the lithosphere is sensitive to the imposed stress regime, then it may vary in time and produce distinctive geomorphic responses. Such effects will be at their most crucial …

The first glaciers at Ivrea, southern Alpine Foreland  Open
Pleistocene Glaciations and their effects on Alpine topography have drawn scientific attention since well before the days of Penck and Brückner (1909), although this indomitable pair left a strong legacy to build upon. The onset of la…

Spatially variable sea level response to erosion and deposition in Aotearoa New Zealand Open
Surface processes alter sea level by warping Earth’s surface and modifying the gravitational field. Recent studies show that paleo-sea level indicators are depressed by sedimentation near major depocenters, such as the Mississippi an…

Early Pleistocene onset of glacial incision in the Baltic Basin revealed by 10Be-26Al burial dating of the Hattem Beds Open
In Northwest Europe, the earliest presence of the Fennoscandian Ice Sheet (FIS) is registered in the Dutch-German border region, where fluvio-deltaic sediments of the ancient Eridanos river system contain weathered Nordic erratics within t…

Redrawing early human dispersal patterns with cosmogenic nuclides  Open
Burial dating with two cosmogenic nuclides (e.g. 26Al and 10Be) is unveiling the last 5 million years of the sedimentary record. There is no dating method of comparable reliability for the fragmentary records typical of terrestrial setting…

Unveiling the early Eurasian glaciations with new advances of 10Be-26Al burial dating Open
Cosmogenic nuclide burial dating exploits the differential decay rate of a nuclide pair, typically 26Al and 10Be. There are three basic approaches; simple burial dating, the isochron method and P-PINI (Particle Pathway Inversion of Nuclide…

Human dispersals out of Africa via the Levant Open
Homo sapiens dispersed from Africa into Eurasia multiple times in the Middle and Late Pleistocene. The route, across northeastern Africa into the Levant, is a viable terrestrial corridor, as the present harsh southern Levant would probably…

Optimising global landscape evolution models with <sup>10</sup> Be Open
By simulating erosion and deposition, landscape evolution models (LEMs) offer powerful insights into Earth surface processes and dynamics. Stream-power-based LEMs are often constructed from parameters describing drainage area (m), slope (n…

Ice-buttressing-controlled rock slope failure on a cirque headwall, Lake District, UK Open
Rock slope failures in the Lake District, UK, have been associated with deglacial processes after the Last Glacial Maximum, but the controls and timing of the failures remain poorly known. A cirque headwall failure was investigated to dete…

Absence of Large‐Scale Ice Masses in Central Northeast Siberia During the Late Pleistocene Open
Ongoing speculation regarding the existence of large Late Pleistocene ice masses in Northeast Eurasia reflects the dearth of age constraints on glaciations across this vast region. Here, we report the first dates from the central part of N…
