From simple considerations we propose a revision of the AcceleratingMoment Release (AMR) methodology for improving our knowledge of seismic sequences and then, hopefully in a close future, to reach the capability ofpredicting the main-shock location and occurrence with sufficient accuracy. The proposed revision is based on the introduction of a “reduced” Benioff strain for the earthquakes of the seismic sequence where, for the samemagnitude and after a certain distance from the main-shock epicentre, the closer the events the more they are weighted. In addition,we retain the usual expressions proposed by the ordinary AMRmethod for the estimationof the corresponding main-shock magnitude, although this parameter is the weakest of the analysis. Then, we apply the revised method to four case studies in Italy, three of which are the most recent seismic sequences ofthe last 9 years culminating with a shallow main-shock, and one is instead a 1995–1996 swarm with no significant main-shock. The application of the R-AMRmethodology provides the best results in detecting the precursoryseismic acceleration,when comparedwith those found by ordinaryAMR technique.We verify also the stability of the results in space, applying the analysis to real data with moving circles in a large area around each mainshockepicentre, and the efficiency of the revised technique in time, comparing the results with those obtained when applying the same analysis to simulated seismic sequences
