This paper describes the preliminary results of seismic survey performed in the area of Sos­Enattos mine (Lula, NU), by installing a linear array consisting of five short­term mobile stations. The aim was to acquire both environmental seismic noise signals and signals from an active seismic source generated by the blast of explosive charges placed inside the mine. The spectral analyses of seismic noise highlight the presence of a dominant low­frequency peak due to the marine microsism. A propagation velocity of P waves equal to 4500 m/s was estimated by analyzing the first arrivals of the seismic signal deriving from the explosion. Finally, using techniques of analysis of the local seismic response it was possible to obtain preliminary indications on the structure of the subsoil.
