Swelling clay slows landslides

Rainfall can trigger landslides, and it can also cause slow-moving slides to speed up. But researchers have observed that rain also appears to cause landslides composed of clay-rich material to take longer to start moving, and to move slower than expected.

Slumgullion: Colorado's natural 'lab' offers insights into landslides worldwide

In southwestern Colorado, a centuries-old landslide (first identified as such in 1883 by an infamous prospector and purported cannibal) is offering geologists an ideal laboratory to study slow-moving slides.

Creeping danger: Landslide threatens Peruvian village, especially when the earth quakes

A massive landslide has been encroaching on the village of Maca, Peru, since the 1980s. Today, it provides geologists with a laboratory to study slow-moving landslides, especially how they react to rainfall and earthquakes.

How do earthquakes impact landslides?

Sensitive instruments installed on and near the slow-moving landslide in Maca, Peru, have allowed scientists to observe the response of the landslide to earthquakes: information that can help researchers predict hazards from other slow-moving landslides in the region and perhaps around the world. But scientists are wondering whether the findings could also shed light on the triggering of fast-moving landslides by earthquakes.
