Tab. 1 – The nine parameters of each rectangular faults used in the analysis. The first three columns (Lat, Long, depth) identify the center of the rectangular fault. The last column gives the product of the previous three columns (slip area x slip rate) times the shear modulus = 30 GPa. Uncertainties (1 ), in the sense of square root of the corresponding element in the variance covariance matrix scaled by the r.m.s. of the post fit residuals, are: 0.05 deg for Longitude and Latitude, 2 km for depth, 3 degrees for strike and dip, 0.005 m/yr for slip, 5 km and 2 km for Length and respectively Width of the fault.
