Archives and libraries were visited to find previously unknown documents testifying to the Lurøy, Norway, earthquake of 31 August 1819 in northernmost continental Europe. 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 Västerbotten. We found no original Russian documentation but uncovered national newspapers that are more reliable than the previously used Parisian newspaper.To increase transparency, we provide the first list of macroseismic data points (MDPs) including the respective documentation that testify to the Lurøy 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±0.2⁠, 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 Lurøy earthquake.

重新评估1819年8月31日在挪威的Lurøy地震

参观了档案馆和图书馆，以查找以前未知的文件，这些文件证明了1819年8月31日在欧洲最北端的挪威卢罗伊（Lurøy）地震。这里的重点是瑞典，芬兰和俄罗斯，这对于确定挪威东部的可感知范围很重要。新的书面资料包括原始档案文件中的12条笔记或条目，6份当代报纸报道以及两年后写下的回忆。揭露的原始文件有助于确定芬兰和瑞典观测的真实性。原始文档的日期允许以书面形式追踪从目睹的内部区域向南到较大的文档和人口中心的目击者证言的传播。新的信息来源包括瑞典皇家科学院的天气报告，会议纪要以及发送给芬兰参议院的信件。该学院的会议记录表明，瑞典的韦斯特博滕省已收集了足够的数据。我们找不到原始的俄罗斯文献，但发现了比以前使用的巴黎报纸更可靠的国家报纸，为提高透明度，我们提供了第一份宏观地震数据点（MDP）列表，其中包括证明卢瑞地震的各种文献。在可获得足够信息的情况下，使用1998年欧洲宏观地震量表将宏观地震强度分配给一个地区。考虑到强度评估的不确定性，估计的大小为弯矩大小M = 5.9±0.2⁠，再次确认芬诺斯坎迪亚（Fennoscandia）历史地震记录中的最大陆上或近岸地震排名。除了重新评估1819年8月31日的地震外，还提供了1819年2月17日地震的大地震图，在芬兰北部和瑞典都可以感受到。它的某些MDP先前与Lurøy地震有关。
