Abstract
The apparent strain (seismic efficiency times average strain) associated
with an earthquake can be estimated by comparing the spectral amplitudes
of seismic waves at high frequency to those at low frequency. This
information allows one to compare the relative strength of material
in different source regions. The apparent strains (stresses) associated
with earthquakes on ridges do not differ in the average from those
associated with shallow earthquakes in trenches, which may indicate
that the strength of materials and the rupture mechanism in the two
source regions are the same.
