Source parameters of the Orizaba earthquake of august 28, 1973
The theory and method by which the source parameters of an earthquake can be derived from seismic signals in reviewed. 11 P·wave spectra (short and long period records for each station) are averaged and combined with 11 G2 wave spectra to define the average source spectrum of the Orizaba earthquake...

| Sumario: | The theory and method by which the source parameters of an earthquake can be derived from seismic signals in reviewed. 11 P·wave spectra (short and long period records for each station) are averaged and combined with 11 G2 wave spectra to define the average source spectrum of the Orizaba earthquake between periods of 200 sec and 0.5 sec. The seismic moment of this (mb ≈ 6.7) earthquake is determined as 4.8 10₂₆ dyne cm. The corner frequency is 0.1 cps, from which the source radius is estimated to have been 13 km, with a stress drop of 95 bars. |
