At least 14 people are dead and hundreds more missing after a massive landslide in Washington state, crashing and oozing its way through the community of Oso north of Seattle.
While landslides can happen anywhere with elevated terrain, some areas of the nation are more prone to the phenomenon than others.
Regions like the Appalachian Mountains, the Rocky Mountains and the Pacific Coast all have "severe landslide problems," according to the U.S. Geological Survey.
The states of California, Oregon, Washington, Alaska and Hawaii are especially prone, according to the agency.
In fact, the USGS is currently monitoring the following sites for possible landslides because of their history and current geography:
1. Seattle area
2. Highway 50 between Placerville and South Lake Tahoe, Calif.
3. Arroyo Seco near Pasadena, Calif.
4. Chalk Cliffs near Buena Vista, Colo.
5. Jesusita Fire area near Santa Barbara, Calif.
6. Gap Fire area near Goleta, Calif.
7. Dunsmore Canyon near Glendale, Calif.
8. Devil's Punchbowl landslide in Lincoln County, Ore.
9. Carmel Knoll landslide in Lincoln County, Ore.
10. Johnson Creek landslide near Newport, Ore.
11. Elliott State Forest in Oregon
12. Portland, Ore.
