在地震学文献中，1117年1月3日的地震代表了一个有趣的案例研究，无论是从世纪修道院记录的地震发生地区的规模，还是从所提到的破坏程度来看。1117年的地震已经被列入欧洲五个国家（意大利、法国、比利时、瑞士和伊比利亚半岛）的地震目录，它是意大利北方历史上最大的地震。我们分析了12世纪世纪修道院的时间系统，并通过对资料来源的比较分析，将上述两次地震（1月3日夜间和下午）与地域效应联系起来，试图使欧洲的整体情况更加一致。语言指示和影响的局部化之间的联系使我们能够以合理的近似程度揭示两次以前鲜为人知的地震，可能是由一系列事件引起的。在德国南部发生的第一次地震（I 0（震中烈度）VII-VIII MCS（Mercalli，Cancani，Sieberg），M 6.4）比北方意大利（维罗纳地区）发生的更为猛烈的地震早了大约12-13个小时。第二个事件是文献中报告的事件。我们提出了这次维罗纳地震（I 0 IX MCS，M7.0）的新参数。第三次地震在托斯卡纳西北地区独立记录（Imax VII-VIII MCS），但对于后一次事件，震中和震级无法评估。
In the seismological literature the 3 January 1117 earthquake represents an interesting case study, both for the sheer size of the area in which that event is recorded by the monastic sources of the 12th century, and for the amount of damage mentioned. The 1117 event has been added to the earthquake catalogues of up to five European countries (Italy, France, Belgium, Switzerland, the Iberian peninsula), and it is the largest historical earthquake for northern Italy. We have analyzed the monastic time system in the 12th century and, by means of a comparative analysis of the sources, have correlated the two shocks mentioned (in the night and in the afternoon of 3 January) to territorial effects, seeking to make the overall picture reported for Europe more consistent. The connection between the linguistic indications and the localization of the effects has allowed us to shed light, with a reasonable degree of approximation, upon two previously little known earthquakes, probably generated by a sequence of events. A first earthquake in lower Germany (I0 (epicentral intensity) VII–VIII MCS (Mercalli, Cancani, Sieberg), M 6.4) preceded the far more violent one in northern Italy (Verona area) by about 12–13 hours. The second event is the one reported in the literature. We have put forward new parameters for this Veronese earthquake (I0 IX MCS, M 7.0). A third earthquake is independently recorded in the northwestern area of Tuscany (Imax VII-VIII MCS), but for the latter event the epicenter and magnitude cannot be evaluated.
