We use a standard methodology in which regional distance ground motions recorded on very broadband instruments are inverted for slip following the representation theorem for an elastic dislocation.  We use a variety of simplifying assumptions including constant rupture velocity and dislocation rise time.  We further apply slip positivity, seismic moment minimization and smoothing constraints to provide stability to the inversion.
	The simulation of near-source strong ground motions in our methodology involves either:
	1. The application of a directivity capable attenuation relationship such as that determined by Somerville et al.      (1997)
	2. Or solves the forward problem (above) using Green’s functions appropriate for the near-source region and      the regionally derived fault slip map.
	We will show that a combination of 1 & 2 to produce a source specific conservative map (largest value of the two methods) produces reasonable ground motions and is found to work well when integrated with observed strong motion values
