Abstract

Abstract

Powerful techniques have been developed for calculating the plane wave response of horizontally layered models. This method is quite general and is widely used in synthetic wave algorithms. Using this method, we can describe the displacements in terms of a linear combination of the moment tensor elements, and the moment tensor for an arbitrarily oriented dislocation can be given by this method. The moment tensor can be used to distinguish natural earthquakes and underground nuclear experiments according to its different elements. In this paper we rewrite the formula and estimate the reliability of the non-double-couple solutions on the basis of error analysis that includes the variance of modeling and of the noise in the data. Our analysis of synthetic data shows that this method is robust and can be used in the real data analyses. The result is significant for monitoring nuclear explosions by using data from just a few monitoring stations or even from a single station.
