Introduction The supplementary material includes three illustrations that help clarify several points in the paper. The files are in tif format. 1. 2006GL028005-fs01.tif Example STF estimation using the R1 arrival observed at station ULN, Ulan Baatur, Mongolia (Gcarc = 57deg, Azimuth = 0N). The top panel shows the observed ground displacements, the middle panel shows the point source response using the global CMT double-couple solution (Mo = 4.0 10^20 N-m), and the lower panel shows the STF obtained by iterative deconvolution. 2. 2006GL028005-fs02.tif Seismic moment estimates obtained by integrating the Rayleigh wave STFs estimated using the Global CMT best double couple geometry. Inset shows the moment distribution, which has a mean of 6.65 x 10^20 N-m and a standard deviation of 1.16 x 10^20 N-m; the median is 6.50 x 10^20 N-m. The values are about 60% larger than the Global CMT moment, which was based on wave periods shorter than 150 s. 3. 2006GL028005-fs03.tif Free-air marine gravity anomaly map [Sandwell et al., 1997]. Gravity anomalies above the accretionary prism suggest a roughness that is similar in character to that in the seismic slip model. Regions of relative gravity high seem to correlate with regions of high seismic moment, but the agreement is not perfect. Seismicity and slip maps are shown as in Figure 1. Reference Sandwell, D.
