Fortunately, the landslides were detected before it occurred, so everyone was evacuated and there were no injuries.
The slides moved at 70 miles per hour and hit 100 mph at times.
It is not unusual for earthquakes to trigger a landslide, but this is the only landslide known to have done the opposite.
Scientists say what is really important is how these slides can help save lives in the future.
“So when this slide occurred, nobody was hurt or killed,” said Jeffrey Moore, an Assistant Professor of Geology at the U of U. “Landslides of this size across the world kill people. They move at extreme speeds and if they're not detected they can be quite deadly.”
