Propagation of distinct Love-wave pulses from regional to teleseismic distances in continental and oceanic environments

Furumura, Takahashi; Kennett, Brian


Surface waves are usually dispersive with long wave trains and steady decay of amplitude with distance. However, if the group velocity is nearly constant for a span of periods a strong pulse is produced that retains its amplitude for large distances. This situation arises for the fundamental mode of Love waves in the period band 40-500 s for crust and mantle structures with a positive gradient of S wave speed in the uppermost mantle. Such a distinct Love-wave pulse with limited dispersion...[Show more]
