Focal Mechanisms of Mw 6.3 Aftershocks from Waveform Inversions, Phayao Fault Zone, Northern Thailand

Figure 3

To understand uncertainty models, calculation of fault-plane solution for stabilities of the focal mechanism is determined from P-wave polarities. The different frequency ranges were tested to compare the inversion results. Positive and negative polarities are marked with white and black circles, respectively. Nodal lines and and axes correspond to space-time grid searches. Acceptable solutions are plotted in black nodal lines and the best fit solution marked as red nodal lines.
