summary Although the aseismicity of Antarctica has been confirmed by IGY observations, small local disturbances, up to magnitude 3, are almost a daily feature of seismograms at Scott Base. S—P intervals of these shocks range from 3 to 38s but half of the shocks recorded have S‐P differences of 4‐6s, values appropriate to the distance of Mt Erebus. An unusual low‐velocity phase ( V ?0.6km/s) is present on many seismograms.
