The yield stress evaluation as a function of water content for slip-prone clayey soils due to rainfall is studied in this work, particularly, the clayey soil from the region Teziutlán-Puebla-México. Yield stress was calculated as a function of water content using the slump test in cylindrical geometry. Results show a critical point of water content where yield stress decreases dramatically, and those values were related to the historical daily rain data. It was found a maximum precipitation millimeters that triggers the landslide, but still is low compared with the historical reported data.
