Grange Orgiera landslide (Varaita Valley, Sampyre (CN) Piedmont, Northern Italy)

The Grange Orgiera landslide is a wide phenomenon of the Western Alps occurred in July 2009, located in Sampeyre municipality (CN, Piedmont), on the left side of the Varaita Valley. This is a complex landslide, in particular, classify as a rotational slide evolved in a flow like landslide. Its activation was related to the extraordinary abundant snowfall of 2008-2009 winter, identified as an anomalous event of the last forty-year of a climatological point of view [on-line report Arpa Piemonte, 2009], and the subsequent snowmelt.

From a geomorphological point of view, this event represent a reactivation of a rotational landslide extended from 2150 m asl to 1720 m asl, close to the Grange Orgiera village. This landslide is included in a more extensive gravitative event, extended from Pian delle Serre (about 2270 m asl) to Villar municipality (about 1100 m asl). Moreover, at the slope scale, these landslides were included in a Deep Seated Gravitational Slope Deformation (DsGSD) of about 20 km2, between Villar and Casteldelfino hamlets.

Starting from July 2009 the Grange Orgiera event was monitored with a topographic monitoring network, located in correspondence of the left frontal lobe of the landslide. The landslide was monitored for two distinct period: from August 2009 to October 2009, and from July 2010 to September 2010.
