Intermediate-term middle-range earthquake predictions in Italy: a review

Italy represents the only region of moderate seismic activity where the M8S and CN algorithms are applied simultaneously for routine monitoring. Significant efforts have been made to minimize the intrinsic space uncertainty of predictions and the subjectivity of the definition of the areas where precursors should be identified. Several experiments have been dedicated to assess the robustness of the methodology against the unavoidable uncertainties in the data. With these results acquired, starting in July 2003, an experiment was launched for the real-time test of M8S and CN predictions.
