Solutions of focal mechanisms with minimum residuals for each event. For each solution, estimated parameters (strike, dip, rake) and RMS residuals of polarization angle differences are listed. Yellow circles denote the P and T axes. Black and red bars denote the observed and theoretical polarization directions, respectively. Gray-shaded areas represent the locations of P or T axes that have residuals within +10Â % from the best solutions
