摘要：

Canadian seismograph network mean body‐wave and surface‐wave magnitudes are computed for 28 earthquakes and 28 nuclear explosions in south‐western North America to test the effectiveness of the surface‐ vs body‐wave discriminant between earthquakes and explosions for purely continental paths. For the present Canadian network, the magnitude threshold of discrimination is about m 4.5. A comparison is made between these and other (intercontinental) surface‐ vs body‐wave relationships by normalizing all data to standard magnitudes. Surface‐wave attenuation for intercontinental paths limits the effectiveness of the discriminant to magnitudes about 1.0 higher than the same recording techniques can achieve for intracontinental paths.
