This electronic supplement contains tables of 1D velocity models used to generate the high-frequency synthetics, and figures of source models and peak ground motion synthetics.
The tables summarize the 1D velocity models used to generate the high-frequency synthetics used in this research. San Diego State University computes the high frequency using a 3D velocity model approach.
Table S1. 1D velocity model used by U.S. Geological Survey–Golden, Colorado (USGSG).
Table S2. 1D velocity model used by the URS Corporation and U.S. Geological Survey–Pasadena, California (URSUSGSP) (embayment sites).
Table S3. 1D velocity model used by URSUSGSP (nonembayment sites).
Characteristics of the modeled sources and ground motions as calculated by the three modelers are shown. We assume that modern seismicity trends are a good indicator of the 1811–1812 seismogenic zone and that events NM1, NM2, NM3—the December, January, and February earthquakes—occurred in the southern, northern, and central segments, respectively.
Figures show slip, rupture time, rise time, and rake.The minimum/mean/maximum are reported above each plot.

Synthetic ground-motion velocities are plotted together with the observed records at different stations for the 2008 M 5.4 Mt. Carmel earthquake. See Figure A1 in the appendix of the main article for the location of the stations displayed. Observed and synthetic peak values are included for each station.
