N2 - In this paper we introduce a simple procedure to identify clusters of multivariate waveforms based on asimultaneous assignation and alignment procedure. This approach is aimed at the identification ofclusters of earthquakes, assuming that similarities between seismic events with respect to hypocentralparameters and focal mechanism correspond to similarities between waveforms of events. Thereforewe define a distance measure between seismic curves in R^d d>=1, in order to interpret and betterunderstand the main features of the generating seismic process.
