Aldercrest-Banyon landslide

The Aldercrest-Banyon landslide was a major slow-moving landslide in the east Kelso, Washington neighborhood of Aldercrest beginning in early 1998 through 1999. The disaster ended up being one of the worst urban landslides in United States history in terms of cost. The landslide is one of the most notable in Washington state, which has many landslides due to its mountainous terrain. The Aldercrest-Banyon landslide was the first landslide disaster in the United States that the Federal Emergency Management Agency (FEMA) declared an official disaster area.[1]
