Abstract Archaeoseismological evidence of a strong earthquake, which probably occurred a year before the 252 CE Mt. Etna eruption, has been uncovered at Santa Venera al Pozzo site, located near to Acireale, along the lower eastern flank of the volcano. The site, known for its remarkable and peculiar hydrothermal fluids emissions exploited for thermal uses since the Greek and Roman age, has been investigated through a multidisciplinary approach by integrating archaeoseismological observations with geological and geochemical surveys. Analysis of the observed damage and deformation at the site suggest a capable fault zone through the area. Geochemical and geological surveys were performed in and around the site and have revealed anomalies of soil CO2 efflux along an known active fault and likely also along some unmapped hidden faults. The chemical and isotopic composition of the emitted fluids suggests that these have not a volcanic origin, but they could be related with a deep tectonic system. The data presented in this paper suggest the occurrence of both exposed and hidden active faults in the area of Santa Venera al Pozzo, which could be linked to the seismic activity that damaged the historical site.

如何在考古遗址中应用多学科方法揭示未知的隐藏断层和历史地震破坏：以公元三世纪中叶为例。埃特纳火山地震（意大利西西里岛东部）

摘要 强烈地震的考古地震学证据，可能发生在公元 252 年前一年。埃特纳火山喷发已在位于火山东下侧靠近 Acireale 的 Santa Venera al Pozzo 遗址发现。该遗址以其自希腊和罗马时代以来用于热能用途的非凡而奇特的热液排放而闻名，已通过多学科方法通过将考古地震观测与地质和地球化学调查相结合进行了调查。对现场观察到的损坏和变形的分析表明，该地区有一个有能力的断层带。在该地点及其周围进行了地球化学和地质调查，并揭示了沿着已知活动断层以及可能沿着一些未映射的隐藏断层的土壤 CO2 流出异常。排放流体的化学和同位素组成表明，这些流体并非源自火山，但可能与深部构造系统有关。本文中提供的数据表明，Santa Venera al Pozzo 地区存在暴露的和隐藏的活动断层，这可能与破坏历史遗址的地震活动有关。
