The source parameters of the Çubukdağ (W. Turkey) earthquake of 1986 October 11

Long period P and SH waveforms and first motion polarities of P waves were used to determine the source parameters of the Çubukdaǧ (in the eastern section of the Büyük Menderes graben) earthquake of 1986 October 11, the waveforms used in this event include the WWSSN, and the digitally recorded seismograms of the DWWSSN, SRO and ASRO networks. the minimum misfit solution obtained by the inversion of teleseismic body waveforms are better constrained that those of the previously published Harvard Centroid‐Moment Tensor solution, and are in good agreement with field observations and the local geometry of the graben.
