A new protocol using the viscous remanent magnetization (VRM) of boulders to date cataclysmic geological events such as tsunamis, glacial floods, and landslides is presented and its performance is assessed against two jökulhlaups (glacial floods) of known age in Iceland. High-intensity jökulhlaups h...

As a result of its mountainous nature, many hydroelectric power stations in the Black Sea region are constructed on rock slopes that require a high degree of engineering. Serious negative impacts related to construction safety, such as slope instabilities, that make the risk encountered excessive ha...

Intense debate surrounds the evolution of grasses in northeast Africa. In this week’s classic #openaccess paper from 2013, Feakins et al. use a combination of plant leaf wax carbon isotopic composition and pollen data from marine sediments to understand how grasses evolved over the last 12 million years.
