Frankel, A., Hartzell, S., Liu, P., and Zeng, Y., 2010, Broadband Synthetic Ground Motion Records: U.S. Geological Survey, https://doi.org/10.5066/F7S75DJ6.
Summary
The dataset contains broadband synthetic ground motion records for three events: 1) 1994 M6.7 Northridge, CA, 2) 1989 M7.0 Loma Prieta, CA, and 3) 1999 M7.5 Izmit, Turkey. For each event, 1D synthetic earthquake ground motion time histories are provided, based on four different methodologies: 1) Frankel, A. (2009). A constant stress-drop model for producing broadband synthetic seismograms: comparison with the next generation attenuation relations, Bull. Seism. Soc. Am. V.99, 664-680. 2) Hartzell, S., M. Guatteri, P. Martin Mai, P. Liu, and M. Fisk (2005). Calculation of broadband time histories of ground motion, part II: kinematic and dynamic modeling using theoretical Green’s functions and comparison with the 1994 Northridge earthquake, [...]

These references give a discussion of each method, which is not repeated here. The synthetics are all unfiltered velocities in units of cm/ sec. Each of the four codes includes a nonlinear soil correction. The codes by Frankel (2009) and Zeng et al. (1994) utilize the approach of Finn et al. (1975), and the codes of Hartzell et al. (2005) and Liu et al. (2006) incorporate the approach of Bonilla (2000). Finn, W. D. L., K. W. Lee, and G. R. Martin (1975).
