To meet the requirement of very high co-registration precision, an improved spectral diversity method was proposed to correct the co-registration slope error in the azimuth direction induced by multiple Sentinel-1A TOPS data frames. All phase jumps that appear in the conventional processing method have been corrected after applying the proposed method. The 2D deformation fields in the east-west and vertical directions are also resolved by combing D-InSAR and Offset Tracking measurements. The results reveal that the east-west component dominated the 2D displacement, where up to 2  m displacement towards the west was measured in the coastal area. Vertical deformations ranging between \u22120.25 and 0.25  m were found. The 2D displacements imply the collision of the Nazca plate squeezed the coast, which shows good accordance with the geological background of the region.<\/jats:p>","DOI":"10.3390\/rs8050376","type":"journal-article","created":{"date-parts":[[2016,5,4]],"date-time":"2016-05-04T10:07:08Z","timestamp":1462356428000},"page":"376","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Continent-Wide 2-D Co-Seismic Deformation of the 2015 Mw 8.3 Illapel, Chile Earthquake Derived from Sentinel-1A Data: Correction of Azimuth Co-Registration Error"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2047-2326","authenticated-orcid":false,"given":"Bing","family":"Xu","sequence":"first","affiliation":[{"name":"School of Geosciences and Info-Physics, Central South University, Changsha 410083, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4575-5258","authenticated-orcid":false,"given":"Zhiwei","family":"Li","sequence":"additional","affiliation":[{"name":"School of Geosciences and Info-Physics, Central South University, Changsha 410083, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangcai","family":"Feng","sequence":"additional","affiliation":[{"name":"School of Geosciences and Info-Physics, Central South University, Changsha 410083, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zeyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Geosciences and Info-Physics, Central South University, Changsha 410083, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qijie","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Geosciences and Info-Physics, Central South University, Changsha 410083, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5412-2703","authenticated-orcid":false,"given":"Jun","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Geosciences and Info-Physics, Central South University, Changsha 410083, Hunan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingguo","family":"Chen","sequence":"additional","affiliation":[{"name":"Beijing Di Kong Software Technology Co., Ltd., Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,5,4]]},"reference":[{"key":"ref_1","unstructured":"Usgs Earthquake Hazards Program, m8.3-48km w of Illapel, Chile, 2015, Available online: http:\/\/earthquake.Usgs.Gov\/earthquakes\/eventpage\/us20003k7a#general_summary."},{"key":"ref_2","unstructured":"Pacific tsunami Warning Center (PTWC) Widespread Hazardous Tsunami Waves Are Possible along the Coast of Chile and Peru, 2015, Available online: http:\/\/ptwc.Weather.Gov\/ptwc\/text.Php?Id=pacific.Tsupac.2015.09.16.2301."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"198","DOI":"10.1038\/nature09349","article-title":"2010 maule earthquake slip correlates with pre-seismic locking of andean subduction zone","volume":"467","author":"Moreno","year":"2010","journal-title":"Nature"},{"key":"ref_4","unstructured":"Usgs Earthquake Hazards Program, m8.3 Coastal Chile Earthquake of 16 September 2015, Available online: http:\/\/earthquake.Usgs.Gov\/earthquakes\/eqarchives\/poster\/2015\/20150916.Php."},{"key":"ref_5","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1016\/j.rse.2011.05.028","article-title":"Gmes sentinel-1 mission","volume":"120","author":"Torres","year":"2012","journal-title":"Remote Sens.
