A marine remote sensing survey, which was carried out to examine a landslide following a 6.2 R earthquake in 1995, that affected the coastal and near-shore delta plain zone on which Helike stood, accompanied by onshore borehole data, enabled us to postulate the geological processes leading to the Helike catastrophe. Helike was initially leveled during a 6 to 6.7 R earthquake; it is postulated to have then submerged following a translational landslide caused by liquefaction. This Helike catastrophe model is consistent with historical sources and current views regarding the expected geological hazards magnitude in the Gulf.<\/jats:p>","DOI":"10.3390\/rs70201263","type":"journal-article","created":{"date-parts":[[2015,1,23]],"date-time":"2015-01-23T11:20:34Z","timestamp":1422012034000},"page":"1263-1278","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["The Disappearance of Helike-Classical Greece\u2014New Remote Sensing and Geological Evidence"],"prefix":"10.3390","volume":"7","author":[{"given":"George","family":"Ferentinos","sequence":"first","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology,  University of Patras, Patras 26504, Greece"}]},{"given":"George","family":"Papatheodorou","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology,  University of Patras, Patras 26504, Greece"}]},{"given":"Maria","family":"Geraga","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology,  University of Patras, Patras 26504, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3012-6865","authenticated-orcid":false,"given":"Dimitris","family":"Christodoulou","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology,  University of Patras, Patras 26504, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3290-5467","authenticated-orcid":false,"given":"Elias","family":"Fakiris","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology,  University of Patras, Patras 26504, Greece"}]},{"given":"Margarita","family":"Iatrou","sequence":"additional","affiliation":[{"name":"Laboratory of Marine Geology and Physical Oceanography, Department of Geology,  University of Patras, Patras 26504, Greece"}]}],"member":"1968","published-online":{"date-parts":[[2015,1,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"663","DOI":"10.1111\/j.1365-246X.1990.tb05577.x","article-title":"Seismicity and associated strain of central Greece between 1980 and 1988","volume":"101","author":"Ambraseys","year":"1990","journal-title":"Geophys.
