The 1703 Mw 6.9 seismic sequence (⁠I0 11 Mercalli–Cancani–Sieberg scale) was one of the most important crises ever occurred in Italy and has left a deep mark on the seismic history of cities and towns of central Italy. Abundant documents testify the damage suffered by the city of Rome during this sequence; however, the descriptions are mainly referred to monumental buildings. For the recent macroseismic practice, such edifices are not statistically representative when used for assessing macroseismic intensity; instead, the information about residential housing provides reliable data especially when using the European Macroseismic Scale 1998. In this work, we show that useful information regarding the ordinary residential stock can be retrieved in the bureaucratic documentation, apparently distant from the repertoires traditionally used for historical seismology studies. In particular, we used administrative acts granted by the government of Rome to authorize maintenance works on the external parts of the buildings, namely the “Lettere Patenti.” The scrutiny of these sources allowed us to enrich the available dataset introducing 93 new damage points found on civil building stock spread in the historic center of Rome. The new dataset contributes to better define the picture of the effects of the 1703 seismic sequence in Rome, which allowed us to assess macroseismic intensity with more confidence.

历史地震学如何从官僚机构中受益：1703年在罗马市的“莱特里·专利”案

1703 Mw 6.9地震序列（I0 11 Mercalli–Cancani–Sieberg规模）是意大利有史以来最重要的危机之一，在意大利中部城镇的地震历史上留下了深刻的印记。大量文件证明了罗马城在此期间遭受的破坏；然而，这些描述主要是针对纪念性建筑。对于最近的大地震实践，当用于评估大地震强度时，这些建筑物在统计上并不具有代表性。相反，有关住宅的信息提供了可靠的数据，尤其是在使用1998年欧洲宏观地震规模时。在这项工作中，我们表明，有关普通住宅存量的有用信息可以在官僚文件中找到，显然与传统上用于历史地震学研究的曲目有所不同。尤其是，我们使用了罗马政府授予的行政行为来授权对建筑物外部（即“ Lettere Patenti”）进行维护。对这些资源的审查使我们得以丰富可用的数据集，引入了在罗马历史中心散布的民用建筑存量上发现的93个新损坏点。新的数据集有助于更好地定义罗马1703年地震序列的影响图，这使我们能够更加自信地评估宏观地震烈度。通过对这些来源的审查，我们得以丰富了可用的数据集，引入了在罗马历史中心散布的民用建筑存量中发现的93个新的损坏点。新的数据集有助于更好地定义罗马1703年地震序列的影响图，这使我们能够更加自信地评估宏观地震烈度。通过对这些来源的审查，我们得以丰富了可用的数据集，引入了在罗马历史中心地区散布的民用建筑库存中发现的93个新的损坏点。新的数据集有助于更好地定义罗马1703年地震序列的影响图，这使我们能够更加自信地评估宏观地震烈度。
