A　loess　landslide　occurred　in　southwestern　China　on　21　September　2016.　The　field　investigation　performed　2　months　after　this　event　revealed　that　this　slope　failure　was　a　partial　reactivation　of　a　landslide　initiated　in　1995,　with　a　first-time　failure　in　1975.　This　landslide　has　been　triggered　three　times,　each　having　a　distinct　mode.　This　study　suggests　that　the　high　groundwater　table　was　a　critical　factor　in　this　landslide　occurrence.
