Data are presented from a preliminary evaluation of seven stations of the Very Long Period Experiment network Australia, Thailand, Alaska, Spain, Israel, Norway, and Ogdensburg. For each station a limited amount of signal and noise data have been digitally processed, and results are shown describing the RMS noise levels, noise spectral content, surface wave detection capability and behavior of the M sub s - m sub b discriminant. Also, preliminary results of a comparison between M sub s computed at 20 and 40 seconds are presented.
