The Prat de Julian landslide (Vence, France) is a rotational landslide, active for around forty years.

Moving a volume of land greater than 1.2 million cubic meters, the landslide affects or is a threat to the safety of around thirty houses and numerous facilities: roads, electrical and water networks, wastewater treatment plant...

The landslide occurs at the interface of a combination of very permeable sand and clay containing unconfined groundwater, and fractured and faulted limestone, less permeable but allowing fluid tranfers deep down.
