How soon does the danger of landslides end after the rain stops?

It’s not possible to exactly predict the number of days or weeks that landslides remain a danger after heavy rain. Residents near mountain slopes, canyons, and landslide prone areas should stay alert even after heavy rain subsides.  

While the likelihood of debris flows begins to decline after a day or more of dry weather, some deep-seated landslides may occur days or even weeks to months after long periods of intense rainfall. A good example of this is the Bluebird Canyon landslide, Laguna Beach, California, which is described in a USGS statement.
