Research on a cliff face in Yosemite National Park finds that when rockfalls happen without an obvious cause, ordinary warming in the Sun could be the culprit.
Scientists used drones, seismic data, and eyewitness accounts to figure out what unleashed an unthinkably large landslide on a spring day in Colorado.
An advanced, process-based model that incorporates typically neglected processes provides new insight into the complex dynamics controlling shallow landslide formation.
Boussinesq-type gravity waves appear to accurately describe vertical motion in granular flows found in geophysics.
New mathematical approach lets researchers analyze potentially unstable slopes in three dimensions without testing every possible landslide shape.
Researchers tracked what happened to the White Salmon River after engineers removed the 100-year-old Condit Dam.
Researchers investigate the strength of Oregon’s coastal hillsides in the face of an earthquake.
Scientists have long known that the Pacific Northwest is vulnerable to massive earthquakes, but newly unearthed data raises questions about the strength and frequency of these quakes.
Rockfalls from steep cliffs pose great hazards to the millions who visit Yosemite Valley each year. Armed with new studies, the National Park Service recently took steps to enhance visitors’ safety.
