Abstract Understanding the long‐term earthquake recurrence pattern at subduction zones requires continuous paleoseismic records with excellent temporal and spatial resolution stable threshold conditions. South central Chilean lakes are typically characterized by laminated sediments providing a quasi‐annual resolution. Our sedimentary data show that lacustrine turbidite sequences accurately reflect historical record of large interplate earthquakes (among others 2010 1960 events). Furthermore,...
Abstract Seismically‐induced event deposits embedded in the sedimentary infill of lacustrine basins are highly useful for palaeoseismic reconstructions. Recent, well‐documented, great megathrust earthquakes provide an ideal opportunity to calibrate seismically‐induced lakes with different characteristics and located settings.

Abstract Landslides are common in aquatic settings worldwide, from lakes and coastal environments to the deep sea. Fast-moving, large-volume landslides can potentially trigger destructive tsunamis. damage disrupt global communication links other critical marine infrastructure. Landslide deposits act as foci for localized, but important, deep-seafloor biological communities. Under burial, landslide play an important role a successful petroleum system. While broad importance of understanding...
Abstract Large prehistoric rockslides tend to occur within spatio-temporal clusters suggesting a common trigger such as earthquake shaking or enhanced wet periods. Yet, assessment remains equivocal due the lack of conclusive observational evidence. Here, we use high-resolution lacustrine paleoseismology evaluate relation between past seismicity and cluster large in Eastern Alps. Temporal spatial coincidence paleoseismic evidence with multiple at ~4.1 ~3.0 ka BP reveals that severe...

The giant 2011 Tohoku-oki earthquake has been inferred to remobilise fine-grained, young surface sediment enriched in organic matter from the slope into >7 km deep Japan Trench. Yet, this hypothesis and assessment of its significance for carbon cycle hindered by limited data density resolution hadal zone. Here we combine new high-resolution bathymetry with sub-bottom profiler images cores taken during 2012-2016 order map first time spatial extent earthquake-triggered event deposit along We...
Hadal trenches are the deepest places on Earth and important foci for natural carbon sequestration. Much of sedimentary sequences that accumulate within hadal have been linked to widespread slope sediment remobilisation events, triggered by subduction zone earthquakes. Therefore, trench deposits may provide valuable insights into hazards posed large earthquakes their implications cycle. Despite this strong societal relevance, no studies date provided necessary coverage understand spatial...
Well-characterised tephra horizons deposited in various sedimentary environments provide a means of synchronising archives. The use as chronological tool is however still widely underutilised southern Chile and Argentina. In this study we develop postglacial tephrochronological model for the Chilean Lake District (ca. 38 to 42°S) by integrating terrestrial lacustrine records. Tephra deposits preserved lake sediments record discrete events even if they do not correspond primary fallout. By...
Strong earthquakes at active ocean margins can remobilize vast amounts of surficial slope sediments and dynamically strengthen the margin sequences. Current process understanding is obtained from resulting event deposits low-resolution shear strength data, respectively. Here we directly target a site offshore Japan where both processes are expected to initiate, that is, uppermost part (15 cm) sedimentary sequence. Based on novel application short-lived radionuclide identified, dated,...
Subaquatic mass movements are common in marine and lacustrine environments, but due to their barely predictable nature, direct observations of these processes limited so that knowledge is only indirectly obtained by investigating the resulting mass-transport deposits (MTDs). Most research focuses on most frontally emergent slides, fast-moving events able generate turbidity currents tsunamis. Geohazards confined slides mechanisms behind typical fold-and-thrust deformation structures however...
In slowly deforming tectonic settings (e.g., European Alps), large earthquakes occur too infrequently to be adequately represented in instrumental and historical records. This leads uncertainties inaccuracies of seismic hazard estimations. To extend the record, lacustrine paleoseismologists usually resort sedimentary archive lakes where can recorded as mass-transport deposits associated turbidites. The imprint shaking is generally more subtle poorly understood small (<2 km2) with...
Deformation of trench-fill sediments at the central Japan Trench axis confirms that coseismic slip during 2011 CE Mw 9.1 Tōhoku-oki earthquake extended to shallowest part megathrust fault, contributing unexpectedly large tsunami followed. Understanding recurrence “slip-to-the-trench” style earthquakes is therefore essential for diagnosing future hazard (and other subduction zones). Thermal biomarkers from décollement indicate similar shallow has occurred repeatedly, but timing not yet been...
