LE INDAGINI ARCHEOSISMOLOGICHE NEL CANTIERE DI PIAZZA MADONNA DI LORETO NEL QUADRO DELLE CONOSCENZE SULLA SISMICITÀ DI ROMA

Archaeoseismological investigations performed in the site of Piazza Madonna di Loreto, in Rome, have provided useful information that can enrich the knowledge about the seismicity that has affected Ancient Rome. In detail, evidence of a sudden episode of collapse of the monumental building located at the investigated site have been found and its origin seems probably to be related to an earthquake occurred around the first half of the ninth century. The historical seismicity catalogues report three events chronologically consistent with the period of the collapse event: the 801, 847 and 848 earthquakes. These considerations have to be considered as preliminary, being the study at an early stage.
