Keeping current with landslide prediction tools

In the United States alone, a few dozen landslide deaths are recorded every year. They often happen when gravity pulls rocks and soil down an unstable slope. The trigger may be caused by natural events like rain or snowmelt. ...

Understanding how hillslopes connect ecosystems

Hillslopes are essential landscape features. They physically tie ridges to valleys and link terrestrial and aquatic ecosystems through sediment, water, and nutrients. Understanding how hillslopes interact is critical to understanding ...

Landslides increasingly threaten the world's urban poor

Over the last fifty years, disasters caused by landslides and floods have become ten times more frequent, despite landslides being significantly underreported in global databases. Worldwide, 4500 people are killed on average ...

Fiber optics open new frontier for landslide monitoring

Reservoirs provide water storage, hydropower, and recreation for local communities. However, adding a reservoir significantly changes a landscape's geological conditions and ushers in new and unpredictable hazards—most ...

Steep mountain slopes have surprisingly long lifetimes

Gravity and rock physics say slopes steeper than about 30°—known as the critical threshold angle, or the angle of repose—shouldn't really exist, yet they do. These steep slopes and near-vertical cliffs can be seen in ...
