“…Chimneys are thus highly porous media, and a subsequent explosion would probably couple much less efficiently, for much the same reason known for alluvium at NTS. 80 Small-scale HE experiments suggest that explosions within a rubble chimney can achieve high decoupling factors. 81 Sykes cites several (unidentified) instances where a nuclear test was conducted in the rubble chimney of a previous test, noting that they did generate smaller than normal seismic waves, reducing m b by a similar amount as for a "poor coupling" medium.…”

“…For the shot point, we use granite specified in MM for the granite shots. As alluvium is not specified in the original MM formulations, we follow the suggestion of Murphy and Bennett [] and scale the source spectrum of tuff by 6.5. We use the free surface effect of Ford et al .…”

We present a method to determine source characteristics of explosions near the Earth's surface. The technique accounts for the reduction in amplitudes as the explosion depth approaches the free surface and less energy is coupled into the ground. We apply the method to the Humming Roadrunner series of shallow explosions in New Mexico where the yields and depths are known. Knowledge of the material properties is needed for both source coupling/excitation and the free surface effect. Although there is the expected trade‐off between depth and yield, the estimated yields are close to the known values when the depth is constrained to the free surface. We then apply the method to a regionally recorded explosion in Syria. We estimate an explosive yield less than the 60 t claimed by sources in the open press. The modifications to the method allow us to apply the technique to new classes of events.
