Paper online:

Just published in BSSA, we quantify variations in source parameter estimates at closely spaced stations. Accurate estimates of course parameters and their uncertainties are essential, particularly when the results are used in the comparisons among different studies over a range of earthquake magnitudes and locations.

We use an empirical Green’s function method to spectra estimated using the seismic coda to investigate earthquake source scaling. Our data span a magnitude range from Mw 3.0–Mw 7.1. We find that a constant scaled energy provides a reasonable fit to the data, with no dependence of scaled energy on seismic moment. Published in JGR. g can be generated from ambient noise. Figure above shows the IRF of the Factor Building in UCLA at two different frequency bands.
