Past climate change affected mountain building in the Andes

Climate change can affect the tectonic processes that deform Earth's surface to build mountains. For instance, in actively deforming mountain ranges such as the North Patagonian Andes, erosion caused by increased rainfall ...

Ground shaking during devastating flood offers new insights

A devastating wall of water gushed down the Bhotekoshi/Sunkoshi River in Nepal on July 5, 2016. It came from a lake that had been dammed by a glacial moraine, but the dam broke and discharged more than 100,000 tons of water ...

Scientists find formula for rate of glacial erosion

It's a truism that mathematical relationships are present nearly everywhere in nature, probably more than we realise. The latest place they have turned up is on the underside of glaciers.

Large Landslides lie low: Himalaya-Karakoram ranges

Large landslides are an important process of erosion in the Himalaya-Karakoram ranges (HKR). These high-relief landscapes are characterized by steep slopes that are prone to frequent landsliding. By mapping nearly 500 large ...

Tectonic stress feedback loop explains U-shaped glacial valleys

In the shadow of the Matterhorn, the broad form of the Matter Valley—like so many throughout the Alps—is interrupted by a deep U-shaped glacial trough. Carved into a landscape reflecting millennia of tectonic uplift and ...
