44 GNGTS 2015 S essione 1.1 seismic events that, each time, have partly allowed the freezing of the buildings history below their own rubble. Although sometime the unraveling of this tangled skein of construction/ destruction events is a very hard task, we have collected several indications from different sectors of the town that suggest the occurrence of different earthquakes striking Volcei/ Buccino in the past. Leaving aside the destruction of the sacred structures of Santo Stefano, occurred in the late third century BC event in an area widely affected by earth flow and landslides, our data indicate a strong, destructive event occurred in the second half of the 1 st century AD. This earthquake, which is unknown to the seismological compilations, could be related to the one found by means of paleoseismological analyses across the Mount Marzano Fault System (MMFS in Fig. 1; Galli and Peronace, 2014), i.e. the same structure that caused the 1980 earthquake. Alongside the archaeoseismic indications, this event is recorded by an epigraph that, although incomplete, clearly mention the collapse of the Caesareum. A very speculative hypothesis concerning this event is suggested by its concurrence with the so-called Pompei earthquake in 62 AD. As the strong earthquakes sourced by the Mount Marzano Fault System always induce high intensity effects in the Naples area (e.g., 7 MCS degree in both 1694 and 1980 events), it could be possible that the damage quoted by the historical sources in the ancient Pompei, as in Naples, Ercolano and Nocera (e.g., Seneca in his Naturales quaestiones ) was the far-field effects of the same Irpinia earthquake that struck Volcei. Another disruptive event, or perhaps two occurred close-in-time, is supported by the collapses and reconstructions datable around the year 1000 AD, that we have associated to the known 989 earthquake and/or to an unknown event around 1120. More archaeoseismic indications related to later earthquakes, such as the 1466, 1561 and 1857 events, were not presented here, but together with those that we have discussed strengthen the ability of archaeoseismology in identifying and dating strong shaking events which are not recorded, or are poorly constrained in the current seismic compilation.
