—The development of the digital seismic network in the Azores Archipelago during recent years made it possible to obtain the amplitudes (waveform) of recorded motion in a large set of stations. With this new data, maximum amplitudes of the Wood Anderson seismograph are computed, for each station/component, which, together with epicentral distances, allows for the estimation of local magnitude ML. We used data recorded in 8 digital permanent three-component stations, with inter-station’s distances up to 300 km, in the period June 1998 – June 2000, corresponding to a set of 1315 events with magnitude (ML or MD) 2
