来自亚平宁山脉中部和阿尔卑斯山脉中东部的四个意大利案例表明，如何利用考古地震学和古地震学对变形的考古遗迹进行调查，可能会提高对长期地震活动的认识。在Fucino平原（亚平宁山脉中部），一条罗马运河（建于公元1 - 2世纪）的位移是由影响盆地的活动断层的运动引起的。古地震学分析和现有的考古数据允许日期的事件在公元5 - 6世纪，并假设这场地震也是造成重大损害的竞技场在罗马公元508年前不久。在Egna遗址（博尔扎诺省，北方意大利），古罗马建筑的位移进行了古地震学研究。它可能是由地表断层作用引起的，因此可以假设在一个地震活动性没有显示出重大历史地震的地区发生了强震。在苏尔莫纳平原（亚平宁山脉中部），公元世纪中期左右发生了一次强烈的地震，这一点可以通过碑文得到证实。大量的建筑、倒塌和废弃的证据覆盖了许多考古调查的遗址，并证实了从碑文中推断的发生年代。在特伦托地区（意大利北方），地震对中世纪建筑造成的破坏证据表明，1117年影响意大利北方的地震可能也对阿迪杰山谷造成了重大破坏。所获得的经验表明，在历史研究对了解强震影响没有重大贡献的地区，利用过去地震的考古证据可能是获得与中-大震级事件有关的历史地震活动信息的宝贵工具。
Four Italian cases from central Apennines and central-eastern Alps show how the use of archaeoseismology and paleoseismological investigations on deformed archaeological remains may improve the knowledge on long-term seismicity. In the Fucino Plain (central Apennines), the displacement of a Roman canal (built during the lst-2nd century AD) was caused by the movement of one of the active faults affecting the basin. The paleoseismological analysis and available archaeological data permitted to date the event at the 5th-6th century AD and to hypothesise that this earthquake was also responsible for significant damage to the Colosseum in Rome shortly before 508 AD. At the Egna site (Bolzano province, northern Italy), the displacement of a Roman building has been paleoseismologically investigated. It probably resulted from surface faulting, thus permitting to hypothesise the occurrence of strong earthquakes in an area for which seismicity does not show significant historical earthquakes. In the Sulmona Plain (central Apennines) the occurrence of a strong event around the middle of the 2nd century AD is testified by ah epigraph. Widespread evidence of building, collapses and abandonments characterise a number of archaeologically investigated sites and confirm the age of occurrence inferred from the epigraph. In the Trento area (northern Italy), evidence of earthquake-induced damage to medieval buildings suggests that the earthquake which affected northern Italy in 1117 may have been responsible for significant damage also in the Adige Valley. Gained experience indicates that in areas where historical research does not contribute significantly to the knowledge of the effects of strong earthquakes, the use of archaeological evidence of past earthquakes may be a valuable tool to obtain information on the historical seismicity related to moderate-large magnitude events.
