The extraordinary runout of the associated pyroclastic flows was never observed during the past dome collapse events in 1991 or 2004\u20132005. Based on Satellite Pour l\u2019Observation de la Terre (SPOT) and Earth Observing-1 (EO-1) ALI (Advanced Land Imager), the chronology of the different eruptive phases from September 2014 to September 2016 is reconstructed here. A digital image segmentation procedure allowed for the mapping of the trajectory of the lava flows emplaced on the main cone as well as the pyroclastic flow deposits that inundated the Montegrande ravine on the southern flank of the volcano. Digital surface models (DSMs) obtained from SPOT\/6 dual-stereoscopic and tri-stereopair images were used to estimate the volumes of some lava flows and the main pyroclastic flow deposits. We estimated that the total volume of the magma that erupted during the 2014\u20132016 event was approximately 40 \u00d7 107 m3, which is one order of magnitude lower than that of the 1913 Plinian eruption. These data are fundamental for improving hazard assessment because the July 2015 eruption represents a unique scenario that has never before been observed at Volc\u00e1n de Colima. Volume estimation provides complementary data to better understand eruptive processes, and detailed maps of the distributions of lava flows and pyroclastic flows represent fundamental tools for calibrating numerical modeling for hazard assessment. The stereo capabilities of the SPOT6\/7 satellites for the detection of topographic changes and the and the availability of EO-1 ALI imagery are useful tools for reconstructing multitemporal eruptive events, even in areas that are not accessible due to ongoing eruptive activity.<\/jats:p>","DOI":"10.3390\/rs11101167","type":"journal-article","created":{"date-parts":[[2019,5,16]],"date-time":"2019-05-16T11:21:22Z","timestamp":1558005682000},"page":"1167","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Chronology of the 2014\u20132016 Eruptive Phase of Volc\u00e1n de Colima and Volume Estimation of Associated Lava Flows and Pyroclastic Flows Based on Optical Multi-Sensors"],"prefix":"10.3390","volume":"11","author":[{"given":"Norma","family":"D\u00e1vila","sequence":"first","affiliation":[{"name":"Laboratorio de Ciencia y Tecnolog\u00eda de Informaci\u00f3n Geogr\u00e1fica, Facultad de Geograf\u00eda, Universidad Aut\u00f3noma del Estado de M\u00e9xico, Toluca 50100, Estado de M\u00e9xico, Mexico"}]},{"given":"Lucia","family":"Capra","sequence":"additional","affiliation":[{"name":"Centro de Geociencias, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Juriquilla, Quer\u00e9taro 76230, Mexico"}]},{"given":"Dolors","family":"Ferr\u00e9s","sequence":"additional","affiliation":[{"name":"Centro de Geociencias, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Juriquilla, Quer\u00e9taro 76230, Mexico"}]},{"given":"Juan Carlos","family":"Gavilanes-Ruiz","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias, Universidad de Colima, Colima 28045, Mexico"}]},{"given":"Pablo","family":"Flores","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Recepci\u00f3n M\u00e9xico (ERMEX), 22a Zona Militar SEDENA, Sta Ma.
