Nine major earthquakes that affected the islands of Corfu, Paxoi, Lefkada, Kephalonia, Ithaca, and Zakynthos in the Ionian Sea offshore western Greece at the time of British Protectorate of the United States of the Ionian Islands (1815–1864) have been reappraised by means of a systematic investigation of contemporary, locally produced documents of diverse typologies. With an in‐depth study of the earthquakes attested by multiple observations, this article complements and concludes the research focused on 50 yr of seismic records that was introduced by my recent companion article on the solitary records of earthquake effects throughout the Ionian Islands. Although some earthquakes discussed in this article had already been studied and interpreted in modern times, the exclusive use of carefully contextualized and independent records of earthquake effects allowed the author to overcome the imprecisions of preceding interpretations. Because of the exhaustive documentation, this study proposes a different vision of the characteristics of these nine major earthquakes from their dates of occurrence to newly assigned sets of intensity data.

1815年至1864年，美国爱奥尼亚群岛发生9次重大地震

在爱奥尼亚群岛美国保护国时期（1815-1864年），希腊西部近海的爱奥尼亚海影响科孚岛，帕克索伊，莱夫卡达，凯法利尼亚岛，伊萨卡岛和扎金索斯岛的九次大地震已被重新评估。对当代当地生产的各种类型文献进行系统调查的手段。通过对多种观测证明的地震的深入研究，本文补充并总结了我最近的一篇有关整个爱奥尼亚群岛地震影响的单独记录的文章介绍的针对50年地震记录的研究。尽管本文已经讨论了一些地震，但在现代已经对其进行了解释，独家使用经过仔细语境化和独立的地震影响记录可以使作者克服先前解释的不精确性。由于文件详尽，本研究对这9次大地震的特征提出了不同的见解，从发生日期到新分配的强度数据集。
