The pianura padana emiliana earthquake

Riportiamo gli estratti di due articoli del Focus sul terremoto che ha colpito la pianura dell’Emilia Romagna nel maggio del 2012, tratto dalla rivista bimestrale dell’ENEA “Energia, Ambiente e Innovazione”. Il terremoto dell’Emilia Romagna è stato caratterizzato dal fenomeno della liquefazione del terreno e da gravi danni al patrimonio culturale (chiese, castelli, edifici storici) e agli edifici industriali, ponendo in rilievo l’importanza della prevenzione sismica di tali strutture. Queste le problematiche considerate negli articoli del Focus in questione, in cui sono riportati i principali risultati delle attività svolte immediatamente dopo il terremoto. È possibile scaricare i contenuti del Focus dal sito dell’ENEA.

The main characteristics of May 2012 seismic sequence have been analyzed. The comparison of data from macroseismic surveys and historical information on the main events that struck the area in the past has shown that the present sequence was the most violent in the last 500 years, highlighting the possible criticality in this sector of the Italian territory seismic hazard assessment.
Finally, the analysis of some accelerometric recordings has revealed that the response spectra close to the epicenter exceed technical code design provisions, while heavy damage is also present where response spectra are far lower than code provisions; some considerable damage to both civil and industrial buildings can be explained by the ground motion characteristics.

Damage to religious buildings due to the Pianura Padana Emiliana earthquake

The paper reports the most common mechanisms of damage in churches, oratories and steeples as a result of the damage survey carried out by ENEA researchers in the areas of Emilia-Romagna region affected by the earthquake of May 2012, with particular reference to the historical centres. The surveys, mainly carried out immediately after the event, concerned the mere observation of the damage from the outside. Considering the great extent of the area affected, from the province of Ferrara to those of Bologna and Modena, and the large number of churches in any Italian town, it is easy to imagine the amount of damage caused by this earthquake to religious, architectural and artistic heritage. The earthquake showed the high vulnerability of the religious heritage of Emilia-Romagna and, more generally, of the Italian heritage, mostly located in areas of high seismicity, too often subject only to unsystematic interventions of repair, consolidation, renovation.
