Abstract: | The small amplitudes of surface waves for intermediate and deep-focus earthquakes lead to too low values of the surface-wave magnitudes. On the basis of available material, average magnitude corrections are deduced, which increase with focal depth and amount to 0.1–0.5 for focal depths of 50 100 km and to 0.5–0.7 for depths of 100–700 km. |
