Leaking modes of Love waves and seismogram interpretation
Radovich, Barbara Jean

Leaking modes of Love waves are investigated for a simplified continental, crust-mantle model. The scheme of Rosenbaum (196) is used, whereby the and k are complex numbers and the group velocity is purely real. The dispersion curves are plotted, and group velocities well below the Airy phase of the normal modes are found. Group velocities of 1.-3.8 km/sec attenuate the least, but even these decay to such an extent at 1 km. from the epicenter, that leaking modes of Love waves will never make a contribution to the seismic record.
