U.S. Geological Survey scientists reveal that earthquake shaking in the eastern United States can travel much farther and cause damage over larger areas than previously thought. New research found that M 5.8 earthquake, that struck Virginia on August 23 last year, triggered landslides at distances four times farther and over an area 20 times larger than previous research has shown.rea. According to Edwin Harp, USGS scientist and co-author of this study, the landslide distances from last year’s Virginia earthquake are remarkable compared to historical landslides across the world and represent the largest distance limit ever recorded.
