EN evaluation is based on a new concept of time, termed \u2019natural time\u2019. EN employs natural time, and uniquely estimates seismic risk by means of the earthquake potential score (EPS), which has been found to have useful applications both regionally and globally. Amongst these applications, here we focused on Greece since 2019, for the estimation of the EPS for the largest-magnitude events, MW(USGS) \u2265 6, that occurred during our study period: for example, the MW= 6.0 WNW-of-Kissamos EQ on 27 November 2019, the MW= 6.5 off-shore Southern Crete EQ on 2 May 2020, the MW= 7.0 Samos EQ on 30 October 2020, the MW= 6.3 Tyrnavos EQ on 3 March 2021, the MW= 6.0 Arkalohorion Crete EQ on 27 September 2021, and the MW= 6.4 Sitia Crete EQ on 12 October 2021. The results are promising, and reveal that the EPS provides useful information on impending seismicity.<\/jats:p>","DOI":"10.3390\/e25020379","type":"journal-article","created":{"date-parts":[[2023,2,20]],"date-time":"2023-02-20T03:56:07Z","timestamp":1676865367000},"page":"379","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Earthquake Nowcasting: Retrospective Testing in Greece"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1047-7836","authenticated-orcid":false,"given":"Gerasimos","family":"Chouliaras","sequence":"first","affiliation":[{"name":"Institute of Geodynamics, National Observatory of Athens, 118 10 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1269-4903","authenticated-orcid":false,"given":"Efthimios S.","family":"Skordas","sequence":"additional","affiliation":[{"name":"Section of Condensed Matter Physics and Solid Earth Physics Institute, Department of Physics, National and Kapodistrian University of Athens, Panepistimiopolis Zografos, 157 84 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8483-519X","authenticated-orcid":false,"given":"Nicholas V.","family":"Sarlis","sequence":"additional","affiliation":[{"name":"Section of Condensed Matter Physics and Solid Earth Physics Institute, Department of Physics, National and Kapodistrian University of Athens, Panepistimiopolis Zografos, 157 84 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"905","DOI":"10.5194\/nhess-9-905-2009","article-title":"Investigating the earthquake catalog of the National Observatory of Athens","volume":"9","author":"Chouliaras","year":"2009","journal-title":"Nat.
