Abstract: the temporal and spatial evolution of seismicity, a simple cross-correlation technique was applied to a waveform data set of western Alps earthquakes. A selection of events recorded by a reference station of the regional seismic network of North-Western Italy (IGG network) within a particular S-P range was used. The adopted method was tested on 380 events recorded in 1995, allowing for the definition of the critical parameters for an optimal identification of earthquake families. The comparison of the individuated families definition with the relevant epicentres map confirms that, on small scales, the epicentre positions of microearthquakes located by a regional network could be strongly influenced by location errors. The analysis was extended to a more complete data set of 2653 events; 1171 of them were grouped in families. The results demonstrated that our single station method is able to discriminate between closely spaced families on the basis of the position and of the radiation properties.
