Italian CMT Dataset

This dataset is the result of a compilation of all centroid moment tensors computed for the Italian region for the entire period of availability of digital seismographic data, e.g. 1977 to present. It thus includes solutions from the Global CMT Catalog, from the European-Mediterranean RCMT Catalog, from several papers dedicated to these data (e.g. Pondrelli et al., 2006). In addition, the RCMTs computed for the NE Italy, Friuli, 1976 seismic sequence are included (Pondrelli et al., 2001). We make available a wide dataset covering nearly 40 years of seismic activity, more than 700 centroid moment tensors, for shallow and intermediate depth earthquakes, with magnitude between 4.0 to 6.9.
