The landslide, triggered by prolonged rainfall, is constituted by two main adjacent enlarging bodies with a roto-translational kinematics. They activated in sequence and subsequently joined into a large earth flow, channelizing downstream of the Bardea Creek, for a total length of about 3600 m. The displacement rate of this combined mass was quite high, so that the landslide toe evolved with velocities of several tens of meters per day (with peaks of 70\u201380 m\/day) in the first month, and of several meters per day (with peaks of 13\u201314 m\/day) from early May to mid-July 2013. In the crown area, the landslide completely destroyed a 450 m sector of provincial roadway S.P. 101, and its retrogression tendency exposed the villages of Capriglio and Pianestolla, located in the upper watershed area of the Bardea Creek, to great danger. Furthermore, the advancing toe seriously threatened the Antria bridge, representing the \u201cMassese\u201d provincial roadway S.P. 665R transect over the Bardea Creek, the only strategic roadway left able to connect the above-mentioned villages. With the final aim of supporting local authorities in the hazard assessment and risk management during the emergency phase, on 4 May 2013 aerial optical surveys were conducted to accurately map the landslide extension and evolution. Moreover, a GB-InSAR monitoring campaign was started in order to assess displacements of the whole landslide area. The versatility and flexibility of the GB-InSAR sensors allowed acquiring data with two different configurations, designed and set up to continuously retrieve information on the landslide movement rates (both in its upper slow-moving sectors and in its fast-moving toe). The first acquisition mode revealed that the Capriglio and Pianestolla villages were affected by minor displacements (at an order of magnitude of a few millimeters per month). The second acquisition mode allowed to acquire data every 28 seconds, reaching very high temporal resolution values by applying the GB-InSAR technique.<\/jats:p>","DOI":"10.3390\/rs9020165","type":"journal-article","created":{"date-parts":[[2017,2,17]],"date-time":"2017-02-17T12:10:34Z","timestamp":1487333434000},"page":"165","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Monitoring the Rapid-Moving Reactivation of Earth Flows by Means of GB-InSAR: The April 2013 Capriglio Landslide (Northern Appennines, Italy)"],"prefix":"10.3390","volume":"9","author":[{"given":"Federica","family":"Bardi","sequence":"first","affiliation":[{"name":"Department of Earth Sciences, University of Firenze, Via La Pira 4, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federico","family":"Raspini","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Firenze, Via La Pira 4, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8266-2777","authenticated-orcid":false,"given":"William","family":"Frodella","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Firenze, Via La Pira 4, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Lombardi","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Firenze, Via La Pira 4, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimiliano","family":"Nocentini","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Firenze, Via La Pira 4, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Gigli","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Firenze, Via La Pira 4, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8069-3609","authenticated-orcid":false,"given":"Stefano","family":"Morelli","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Firenze, Via La Pira 4, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3718-7748","authenticated-orcid":false,"given":"Alessandro","family":"Corsini","sequence":"additional","affiliation":[{"name":"Department of Chemical and Geological Sciences, University of Modena and Reggio Emilia, Via Campi 103, 41125 Modena, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8684-7848","authenticated-orcid":false,"given":"Nicola","family":"Casagli","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Firenze, Via La Pira 4, 50121 Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,2,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1007\/s10346-005-0033-9","article-title":"Large reactivated landslides in weak rock masses: A case study from the Northern Apennines (Italy)","volume":"3","author":"Borgatti","year":"2006","journal-title":"Landslides"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3237","DOI":"10.1016\/j.rse.2011.07.007","article-title":"Tracking and evolution of complex active landslides by multi-temporal airborne LiDAR data: The Montaguto landslide (Southern Italy)","volume":"115","author":"Ventura","year":"2011","journal-title":"Remote Sens.
