High-arctic fjords, for example, van Keulenfjorden on Spitsbergen, provide valuable palaeoenvironmental archives as they typically contain landforms and sediment sequences that document past changes in glacial activity with high temporal resolution. Van was covered a grounded glacier during the last glacial, it deglaciated between c. 11.8 11.3 cal. ka BP. The retreat of ice front accelerated from approximately 80 to 190 m/a deglaciation. maximum late Holocene extent occurred after surge-like...

Abstract Turbidites embedded in lacustrine sediment sequences are commonly used to reconstruct regional flood or earthquake histories. A critical step for this method be successful is that turbidites and their trigger mechanisms determined unambiguously. The latter particularly challenging prehistoric proglacial lake records high‐seismicity settings where both earthquake‐generated flood‐generated interrupt the background varved sedimentation. This calls a new allow efficient objective...
ABSTRACT Severe storm flooding poses a major hazard to the coasts of north‐western Europe. However, long‐term recurrence patterns extreme coastal and their governing factors are poorly understood. Therefore, high‐resolution sedimentary records past North Atlantic required. This multi‐proxy study reconstructs storm‐induced overwash processes from lake sediments on Shetland Islands using grain‐size geochemical data, re‐analysis historical data. The chronostratigraphy is based Bayesian...
Tidal Lake Hamana is located near the Nankai-Suruga Trough, which repeatedly affected by tsunamogenic megathrust earthquakes. The lake represents a good sedimentary archive for past earthquakes and extreme wave events (EWEs), triggered tsunamis tropical storms (typhoons). By applying broad range of surveying methods, sedimentological analyses dating techniques, 7.5-kyr-long record ≥ 22 EWE deposits was extracted. Event are embedded in fine-grained (silty) lacustrine sediments have...
Abstract On 21 April 2007, an Mw 6.2 earthquake produced unforeseen chain of events in the Aysén fjord (Chilean Patagonia, 45.5°S). The triggered hundreds subaerial landslides along flanks. Some eventually involved a subaqueous component that, turn, generated series displacement waves—tsunami‐like waves by fast entry landmass into water body—within [ Naranjo et al ., 2009; Sepúlveda and Serey , Hermanns 2013]. These waves, with run‐ups several meters high shoreline, caused 10 fatalities. In...
Abstract Determining the aperiodicity of large earthquake recurrences is key to forecast future rupture behavior. Aperiodicity classically expressed as coefficient variation recurrence intervals, though recent trend express it burstiness more intuitive and avoids minor inaccuracies. Due underestimation in records with a low number paradigm obtain long paleoseismic many events. Here, we present suite synthetic designed around Weibull inverse Gaussian distributions that demonstrate age...
Tsunami deposits around the North Sea basin are needed to assess long‐term hazard of tsunamis. Here, we present sedimentary evidence youngest tsunami on Shetland Islands from Loch Flugarth, a coastal lake northern Mainland. Three gravity cores show organic‐rich background sedimentation with many sub‐centimetre‐scale sand layers, reflecting recurring storm overwash and sediment source limited active beach uppermost subtidal zone. A basal 13‐cm‐thick layer, dated 426–787 cal. CE based 14 C,...

X-ray computed tomography (CT) is a non-destructive imaging technique that provides three-dimensional (3D) visualisation and high-resolution quantitative data in the form of CT numbers. numbers are derived from energy, effective atomic number density analysed material. The sensitivity to changes material means it can be used identify facies within sediment cores by detecting downcore shifts properties, quantify skeletal linear extension rates internal biological erosion coral cores. Here we...
Eskers are elongate, straight to sinuous sedimentary ridges deposited in subglacial, englacial or supraglacial drainage networks (e.g. Warren & Ashley 1994). The following four basic esker types distinguished (after 1994; Brennand 2000; Benn Evans 2010): tunnel fills, formed and subglacial conduits exposed by ice ablation; ice-channel sub-aerial, ice-walled channels; segmented during stepwise glacier retreat; beaded eskers, composed of subaqueous fans retreat a water-terminating glacier....
Overlying the subducting Nazca Plate, Chile’s coastline is notoriously prone to megathrust earthquakes and associated tsunamis, as illustrated by 2010 Maule (Mw 8.8) 1960 Valdivia 9.5) events. Despite numerous geophysical paleoseismic studies, many questions remain about timing, location rupture extent of great tsunamigenic earthquakes. To study past tsunami inundation, coastal lakes may form complementary sedimentary archives classical plain studies they have more accommodation...
