A Note on the Seismicity of the Ross Sea Region

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 38 s but half of the shocks recorded have S-P differences of 4–6 s, value...

Description
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 38 s but half of the shocks recorded have S-P differences of 4–6 s, values appropriate to the distance of Mt Erebus. An unusual low-velocity phase (<f> </f>) is present on many seismograms.
