摘要: The Ferrara 2012 seismic sequence was characterized by two main compressional events, which occurred on May 20 and 29, 2012, with Mw 6.1 6.0, respectively (quick Regional Centroid Moment Tensor [RCMT] at http://autorcmt.bo.ingv.it/quicks.html). These events were followed five >5.0 (two three 2012) hundreds of lower magnitudes distributed along a WNW-ESE-elongated area ca. 500 km2 (ISIDe database http://iside.rm.ingv.it/ iside/standard/index.jsp.). ongoing activity the northward-verging fold-and-thrust structures Ferrara-Romagna Arc (Figure 1A) eastward-verging Coastal Adriatic (referred to as Outer Thrust System [OTS] in Lavecchia et al. 2003) has been debated topic Italian literature.
