The analysis of ascending and descending Sentinel-1 orbits (DInSAR) and Global Navigation Satellite System (GNSS) datasets from 2014 to 2019 imaged a radially symmetric inflating area, uplifting at a rate of 35 to 50 mm\/yr and centered 5 km north of Sabancaya. The DInSAR and GNSS data were modeled independently. We inverted the DInSAR data to infer the location, depth, and volume change of the deformation source. Then, we verified the DInSAR deformation model against the results from the inversion of the GNSS data. Our modelling results suggest that the imaged inflation pattern can be explained by a source 12 to 15 km deep, with a volume change rate between 26 \u00d7 106 m3\/yr and 46 \u00d7 106 m3\/yr, located between the Sabancaya and Hualca Hualca volcano. The observed regional inflation pattern, concentration of earthquake epicenters north of the ASVC, and inferred location of the deformation source indicate that the current eruptive activity at Sabancaya is fed by a deep regional reservoir through a lateral magmatic plumbing system.<\/jats:p>","DOI":"10.3390\/rs12111852","type":"journal-article","created":{"date-parts":[[2020,6,9]],"date-time":"2020-06-09T05:16:14Z","timestamp":1591679774000},"page":"1852","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Source Model for Sabancaya Volcano Constrained by DInSAR and GNSS Surface Deformation Observation"],"prefix":"10.3390","volume":"12","author":[{"given":"Gregorio","family":"Boixart","sequence":"first","affiliation":[{"name":"Instituto de Estudios Andinos, Universidad de Buenos Aires-CONICET, Buenos Aires 1428, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4176-7497","authenticated-orcid":false,"given":"Luis F.","family":"Cruz","sequence":"additional","affiliation":[{"name":"Escuela Profesional de Ingenier\u00eda Geof\u00edsica, Universidad Nacional de San Agust\u00edn de Arequipa, Arequipa 04001, Peru"},{"name":"Observatorio Vulcanol\u00f3gico del INGEMMET, Instituto Geol\u00f3gico Minero y Metal\u00fargico, Arequipa 04001, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafael","family":"Miranda Cruz","sequence":"additional","affiliation":[{"name":"Escuela Profesional de Ingenier\u00eda Geof\u00edsica, Universidad Nacional de San Agust\u00edn de Arequipa, Arequipa 04001, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo A.","family":"Euillades","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda, Instituto CEDIAC &amp; CONICET, Universidad Nacional de Cuyo, Mendoza M5502JMA, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leonardo D.","family":"Euillades","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda, Instituto CEDIAC &amp; CONICET, Universidad Nacional de Cuyo, Mendoza M5502JMA, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4726-5287","authenticated-orcid":false,"given":"Maurizio","family":"Battaglia","sequence":"additional","affiliation":[{"name":"US Geological Survey, Volcano Disaster Assistance Program, NASA Ames Research Center, Moffett Field, CA 94035, USA"},{"name":"Department of Earth Sciences, Sapienza-University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,8]]},"reference":[{"key":"ref_1","first-page":"122","article-title":"Geolog\u00eda y evaluaci\u00f3n de peligros del complejo volc\u00e1nico Ampato-Sabancaya (Arequipa)","volume":"61","author":"Rivera","year":"2015","journal-title":"INGEMMET Bolet\u00edn Serie C Geodin\u00e1mica e Ingenier\u00eda Geol\u00f3gica"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"110","DOI":"10.1016\/j.jvolgeores.2016.04.038","article-title":"The eruptive chronology of the Ampato\u2013Sabancaya volcanic complex (Southern Peru)","volume":"323","author":"Samaniego","year":"2016","journal-title":"J.
