Earthquakes present severe hazards for people and economies and can be primary drivers of landscape change yet their impact to river-channel networks remains poorly known. Here we show evidence for an abrupt earthquake-triggered avulsion of the Ganges River at ~2.5 ka leading to relocation of the mainstem channel belt in the Bengal delta.

- Chernozems/Phaeozems are vital agricultural soils with debated origins and ages, found significantly in Central Germany.
- Intensive bioturbation, especially by earthworms, is suggested as the primary natural formation process, with recent studies using single-grain luminescence dating to explore soil development during the Bronze Age.
- The research indicates that Chernozem/Phaeozem formation began in the Early Holocene, prior to significant human settlement, and ceased around 6-5 thousand years ago due to increased humidity, providing insights into prehistoric farming practices.
Article Synopsis
- Luminescence signals from quartz and feldspar are crucial for dating Quaternary sediments, but incomplete bleaching can skew results, especially in river settings.
- Recent studies of the Rangitikei River in New Zealand used feldspar pIRIR dating to investigate the relationship between sediment age and incision rates, revealing a non-linear pattern of landscape changes.
- The presence of unbleached grains in sediments varied with the incision rate, indicating that deposits formed during rapid cutting of the landscape have fewer bleached grains, providing insights into past river transport and landscape evolution.
The manufacture of geometric engravings is generally interpreted as indicative of modern cognition and behaviour. Key questions in the debate on the origin of such behaviour are whether this innovation is restricted to Homo sapiens, and whether it has a uniquely African origin. Here we report on a fossil freshwater shell assemblage from the Hauptknochenschicht ('main bone layer') of Trinil (Java, Indonesia), the type locality of Homo erectus discovered by Eugène Dubois in 1891 (refs 2 and 3).
