New landslides on US West Coast detected by SMU scientists

Team of Dallas-based university researchers use satellite radar imagery to reveal hundreds of unseen landslides occurring in western states

Landslides occur when masses of rock, soil or earth fall down a slope because of gravity. They cause thousands of deaths each year around the world, and in the United States alone, damage exceeds $2 billion annually from these slides.
Examples of active landslides discovered by SAR interferograms. These ten slow-moving landslides were distributed over Washington, Oregon and California. Red polygons outline the landslide extents, and white arrows mark the downslope directions.
