The eastern Molise earthquake had an epicentral intensity of Io=7–8 MCS (Mercalli-Cancani-Sieberg scale) and a maximum intensity of Imax=8–9 in the village of San Giuliano di Puglia. The historical portion of this village, built on a marly limestone hill, had intensities of 6–7 MCS, whereas the most recently developed area, on a crest of marly clays, had a local intensity of I=9–10 MCS, and was almost totally destroyed. Neighboring villages were generally struck with an intensity of 6–7 MCS. In several places, the damage was due to gravity-driven phenomena affecting both the rocky and clayey substratum of the villages. The epicentral area is characterized by the lack of historical earthquakes comparable to the 2002 sequence, having suffered only the effects of distant, strong (M>6.5) events, coming either from the Apennine seismogenic belt or from the Gargano area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
