SUMMARY: Using satellite data, scientists think they might have a way to give some advance warning of landslides, which kill hundreds of people around the world every year. Scientists know that regions which are about to turn into a landslide can shift slightly.

Analysts compare multiple images of the same location which allows them to highlight regions which have shifted slightly.
