2000, Miscellaneous Field Studies Map 2346
Many landslides occurred on the coastal bluffs between Seattle and Everett, Washington during the winters of 1996 and 1997. Shallow earth slides and debris flows were the most common, but a few deep-seated rotational earth slides also occurred. The landslides caused significant property damage and interfered with rail traffic; future...

Map showing inventory and regional susceptibility for Holocene debris flows, and related fast-moving landslides in the conterminous United States
Earl E. Brabb, Joseph P. Colgan, Timothy C. Best
2000, Miscellaneous Field Studies Map 2329
Introduction Debris flows, debris avalanches, mud flows and lahars are fast-moving landslides that occur in a wide variety of environments throughout the world. They are particularly dangerous to life and property because they move quickly, destroy objects in their paths, and often strike without warning. This map represents a significant effort...
