Yield estimation based on calculated comparisons to particle velocity data recorded at low stress
This paper deals with the problem of optimizing the yield estimation process if some of the material properties are known from geophysical measurements and others are inferred from in-situ dynamic measurements. The material models and 2-D simulations of the event are combined to determine the yield. Other methods of yield determination from peak particle velocity data have mostly been based on comparisons of nearby events in similar media at the Nevada Test Site. These methods are largely empirical and are subject to additional error when a new event has different properties than the population being used for a basis of comparison. The effect of material variations can be examined using Lawrence Livermore National Laboratory's KDYNA computer code. The data from the FLAX event provide an instructive example for simulation.
