The focus here is on Sweden, Finland, and Russia, which are important for determining the area of perceptibility east of Norway. The new written sources include 12 notes or entries in original archived documents, six contemporary newspaper reports, and two recollections written down years later. The original documentation uncovered is contributory to establishing the authenticity of the observations in Finland and Sweden. The dates of the original documentation allow tracing of the dissemination of eyewitness accounts in writing from the inner area of perceptibility southward to the larger documentation and population centers. New sources of information include weather reports of the Royal Swedish Academy of Sciences, minutes of its meetings, and correspondence sent to the Senate in Finland. The minutes of meetings of the Academy indicate that ample data were collected in the Swedish province of V\u00e4sterbotten. We found no original Russian documentation but uncovered national newspapers that are more reliable than the previously used Parisian newspaper.<\/jats:p>\n               <jats:p>To increase transparency, we provide the first list of macroseismic data points (MDPs) including the respective documentation that testify to the Lur\u00f8y earthquake. A macroseismic intensity was assigned to a locality, using the European Macroseismic Scale of 1998, when adequate information was available. Accounting for the uncertainty of intensity assessment, the magnitude was estimated as moment magnitude M=5.9\u00b10.2, reconfirming the ranking as the largest onshore or nearshore earthquake in the historical seismicity record of Fennoscandia. In addition to the reappraisal of the 31 August 1819 earthquake, a macroseismic map is provided for the earthquake of 17 February 1819, which was felt in northern Finland and Sweden. Some of its MDPs were previously associated with the Lur\u00f8y earthquake.<\/jats:p>","DOI":"10.1785\/0220190363","type":"journal-article","created":{"date-parts":[[2020,4,8]],"date-time":"2020-04-08T17:10:40Z","timestamp":1586365840000},"page":"2462-2472","source":"Crossref","is-referenced-by-count":21,"title":["A Reappraisal of the Lur\u00f8y, Norway, Earthquake of 31 August 1819"],"prefix":"10.1785","volume":"91","author":[{"given":"P\u00e4ivi B.","family":"M\u00e4ntyniemi","sequence":"first","affiliation":[{"name":"Institute of Seismology, Department of Geosciences and Geography, University of Helsinki, Helsinki, Finland"}]},{"given":"Mathilde B.","family":"S\u00f8rensen","sequence":"additional","affiliation":[{"name":"Department of Earth Science, University of Bergen, Bergen, Norway"}]},{"given":"Tatiana N.","family":"Tatevossian","sequence":"additional","affiliation":[{"name":"Institute of Physics of the Earth, Russian Academy of Sciences, Moscow, Russia"}]},{"given":"Ruben E.","family":"Tatevossian","sequence":"additional","affiliation":[{"name":"Institute of Physics of the Earth, Russian Academy of Sciences, Moscow, Russia"}]},{"given":"Bj\u00f6rn","family":"Lund","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, Uppsala University, Uppsala, Sweden"}]}],"member":"790","published-online":{"date-parts":[[2020,4,8]]},"reference":[{"key":"2020090215495025700_rf1"},{"key":"2020090215495025700_rf2"},{"key":"2020090215495025700_rf3","first-page":"1818"},{"key":"2020090215495025700_rf4"},{"key":"2020090215495025700_rf5"},{"key":"2020090215495025700_rf6","volume-title":"\u00c5bo Tidningar (\u201c\u00c5bo Papers\u201d)","year":"1820"},{"key":"2020090215495025700_rf7","volume-title":"Allm\u00e4nna Journalen","year":"1819"},{"key":"2020090215495025700_rf8","volume-title":"\u0421?\u0435\u0432\u0435\u0440\u043d\u0430\u044f \u043f\u043e\u0447\u0442\u0430 (\u201cNorthern Post\u201d)","year":"1819"},{"key":"2020090215495025700_rf9","volume-title":"Den Norske Rigstidende","year":"1819"},{"key":"2020090215495025700_rf10","volume-title":"Inrikes Tidningar","year":"1819"},{"key":"2020090215495025700_rf11","volume-title":"Le Conservateur Impartial","year":"1819"},{"key":"2020090215495025700_rf12","volume-title":"Le Moniteur Universel","year":"1819"},{"key":"2020090215495025700_rf13","volume-title":"\u041c\u043e\u0441\u043a\u043e\u0432\u0441\u043a\u0438\u0435 \u0412\u0435\u0434\u043e\u043c\u043e\u0441\u0442\u0438 (\u201cMoscow Gazette\u201d)","year":"1819"},{"key":"2020090215495025700_rf14","volume-title":"Stockholms Posten","year":"1819"},{"key":"2020090215495025700_rf15","volume-title":"St. Petersburgische Zeitung (\u201cSt. Petersburg Newspaper\u201d)","year":"1819"},{"key":"2020090215495025700_rf16","volume-title":"Trondhjems Adressecontoirs Efterretninger","year":"1819"},{"key":"2020090215495025700_rf17","volume-title":"Troms\u00f8 Stiftstidende (Troms\u00f8 Tidende)","year":"1842"},{"key":"2020090215495025700_rf18","volume-title":"Uusi Suometar","year":"1882"},{"key":"2020090215495025700_rf19","first-page":"39","article-title":"Norges kraftigste jordskjelv","volume-title":"Lur\u00f8yboka\u201385, \u00c5rbok for Lur\u00f8y","author":"Aasvik","year":"1985"},{"key":"2020090215495025700_rf20","doi-asserted-by":"crossref","first-page":"361","DOI":"10.1002\/eqe.4290130309","article-title":"The seismicity of western Scandinavia","volume":"13","author":"Ambraseys","year":"1985","journal-title":"Earthq.
