They are obtained by integration of data by aerial photogrammetry, terrestrial laser scanning (TLS) and GPS taken in the 1996\u20132011 time span. A comparison between multi-temporal models built from remote sensing data (photogrammetry and TLS) highlights areas characterized by  ~7\u201310 cm\/y positive differences (i.e., elevation increase) in the upper crown of the slope. The GPS measurements confirm these results. Areas characterized by negative differences, related to both mass collapses or small surface lowering, also exist. The higher differences, positive and negative, are always observed in zones affected by higher fumarolic activity. In the 2010\u20132012 time span, ground motions in the northern part of the crater rim, immediately above the upper part of observed area, are also observed. The results show different trends for both vertical and horizontal displacements of points distributed along the rim, with a magnitude of some centimeters, thus revealing a complex kinematics. A slope stability analysis shows that the safety factors estimated from these data do not indicate evidence of possible imminent failures. Nevertheless, new time series are needed to detect possible changes with the time of the stability conditions, and the monitoring has to go on.<\/jats:p>","DOI":"10.3390\/rs5052238","type":"journal-article","created":{"date-parts":[[2013,5,13]],"date-time":"2013-05-13T12:17:01Z","timestamp":1368447421000},"page":"2238-2256","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Remote Sensing and Geodetic Measurements for Volcanic Slope Monitoring: Surface Variations Measured at Northern Flank of La Fossa Cone (Vulcano Island, Italy)"],"prefix":"10.3390","volume":"5","author":[{"given":"Arianna","family":"Pesci","sequence":"first","affiliation":[{"name":"Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Bologna, via Creti 12, I-40127 Bologna, Italy"}]},{"given":"Giordano","family":"Teza","sequence":"additional","affiliation":[{"name":"Dipartimento di Geoscienze, Universit\u00e0 degli Studi di Padova, via Gradenigo 6, I-35131 Padova, Italy"}]},{"given":"Giuseppe","family":"Casula","sequence":"additional","affiliation":[{"name":"Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Bologna, via Creti 12, I-40127 Bologna, Italy"}]},{"given":"Massimo","family":"Fabris","sequence":"additional","affiliation":[{"name":"Dipartimento di Architettura Urbanistica e Rilevamento, Universit\u00e0 degli Studi di Padova, Via Marzolo 9, I-35131 Padova, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0435-7763","authenticated-orcid":false,"given":"Alessandro","family":"Bonforte","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Civile, Edile e Ambientale, Universit\u00e0 degli Studi di Padova, Via Marzolo 9, I-35131 Padova, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2013,5,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"575","DOI":"10.3189\/S0022143000001453","article-title":"Modelling mass balance using photogrammetric and geophysical data: A pilot study at Griesgletscher, Swiss Alps","volume":"45","author":"Funk","year":"1999","journal-title":"J.
