Sediments of Lake Vens (SW European Alps, France) record large-magnitude earthquake events

Palaeoflood activity and climate change over the last 1400 years recorded by lake sediments in the north-west European Alps

Palaeoflood activity and climate change over the last 1400 years recorded by lake sediments in the NW European Alps

A high-resolution sedimentological and geochemical study of a high-altitude proglacial lake (Lake Blanc, Aiguilles Rouges, 2352m a.s.l.) revealed 195 turbidites, 190 of which are related to flood events over the last 1400 years. We used the coarsest sediment fraction of each turbidite as a proxy for the intensity of each flood event. Because most flood events at this locality are triggered by l...

Large-magnitude, transient, bradycardic events in rabbits.

We propose that heart period sequences are organized similarly to sentences, with a lexicon of recurrent, similarly shaped words. These words should fulfill four criteria: universality, nonrandomness, central statistical tendencies, and specific associated physiology. Here we describe a large-magnitude, transient bradycardia (LMTB) and assess whether it constitutes a word. LMTBs were seen in 11...

Variations in radiocarbon ages of various organic fractions in core sediments from Erhai Lake, SW China

Radiocarbon dating was performed for the extracted organic fractions (cellulose-rich and humic acid fractions of plant fragment; fulvic acid, humic acid and humin fractions of humus substance) and shell from core sediments of the Erhai Lake, SW China. The 14C dating results reveal that there are considerable differences, but there apparently is a humic acid ≤ humin < fulvic acid fraction sequen...

Lichen dating of earthquake - generated regional rockfall events , Southern Alps , Geological Society of America

Synchronous regional rockfall events triggered by large earthquakes in the Southern Alps of New Zealand were used to evaluate and improve the lichenometry method for surface-exposure dating. Digital calipers were used to measure the maximum diameter of the largest lichen on many rockfall blocks, using a fixed-area largest-lichen (FALL) sampling strategy. Regional significance of FALL peaks can ...
