THE SOURCE PARAMETERS OF THE SAN FERNANDO EARTHQUAKE INFERRED FROM TELESEISMIC BODY WAVES BY MAX WYss AND THOMAS
نویسنده
چکیده
The accuracy of teleseismic estimates of moment, fault area, dislocation and stress drop was tested for the case of a thrust fault: the San Fernando, California, earthquake of Feburary 9, 1971. On the basis of P-wave spectra of 25 stations and S-wave spectra of 9 stations, the respective values were found to be 0.7.1026 dyne-cm, 570 km 2, 45 cm, and 14 bars. They agree well with the same parameters obtained from field observations. It is concluded that Brune's (1970) seismic source model is valid for the area determination of thrust earthquakes. The energy radiated in the form of S waves is estimated to be 5.1021 ergs.

SOURCE PARAMETERS OF THE BORREGO MOUNTAIN EARTHQUAKE1 By MAx WYss
Spectral analysis of teleseismic body phases at several azimuths was used to determine the moment, fault length, dislocation, stress-drop, and radiated energy of the Borrego Mountain earthquake. The results agree well with the same parameters obtained from the surface fracture and aftershock distribution and local observations of radiated energy.
متن کاملT H E Use of Body-wave Spectra in the Determination of Seismic-source Parameters by Thomas C. Hanks and Max Wyss
Teleseismic determinations of body-wave (P, S) spectra, interpreted in terms of the Brune (1970) seismic-source model, are used to estimate the parameters seismic moment (Mo) and source dimension (r) for three large, shallow, strike-slip earthquakes occurring on nearly vertical fault planes and for which the same parameters can be determined from field (F) data. These earthquakes are (I) the Bo...
