Apparent Stresses of Earthquakes on Ridges compared to Apparent Stresses of Earthquakes in Trenches

Year: 1970

Type: article

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.
