Supplemental Figure 2. Example of synthetic slip model (top) used to evaluate coseismic model resolution. (Bottom) Slip pattern inverted from a synthetic data set produced using the dislocation model of unit slip dislocation patches (the synthetic data are assigned the same variances as the original observations and are perturbed with appropriate Gaussian noise before inversion). Note different color scale for slip in the two plots and that the bottom of the model fault is at a depth of 21 km.

(Bottom) The slip pattern is inverted from a synthetic data set produced using the dislocation model of unit slip dislocation patches (the synthetic data are assigned the same variances as the original observations and are perturbed with appropriate Gaussian noise before inversion). Note different color scale for slip in the two plots and that the bottom of the fault is at 40 km.

Supplemental Figure 4. The difference in range change, along the radar line of sight, between the ERS-1 and GPS determinations. The eastward slope of -0.2 mm/km may be due to orbital errors. Tropospheric artifacts have been observed to correlate with topographic elevation on Mount Etna (F. Beauducel, P. Briole, J. L. Froger, J. Geophys. Res., in press).
