▲ ▲ Figure 5. Observed (black line) and synthetic (dashed line) velocity seismograms computed for the slip model described in the paper;the duration is 30 seconds. Values above the traces are the maximum observed absolute velocities (m/s). The model fits well the onsetpolarities and amplitudes, especially for the vertical components. The top four recordings are from stations located on rock sites orvery shallow soft sites (CMHS); the other ones are located on very soft sites in the plains. A resonant period of about 3 seconds isnoticeable on “soft site” horizontal recordings. A sharp single peak, not modeled by our solution, is also noticeable just prior to the3-second period signal (at 10 seconds on CCCC) on all horizontal components. The amplitude of the peak is actually twice as large forstations further away from the modeled fault plane.Seismological Research Letters Volume 82, Number 6 November/December 2011 787
