Towards a Unified Notation of Source Parameters

Abstract

The displacement field for body waves, surface waves, static deformations and free oscillations are examined in a unified algebraic treatment relating it to the parameters of various source mechanisms. By using a convenient notation of the source parameters θ, δ, λ (representing the strike angle, dip angle and slip angle, respectively), handling of the algebraic expressions becomes simplified. It is shown that the ambiguity between the fault plane and the auxiliary plane exists for all the above-mentioned fields. The various conventions for expressing the parameters and by different authors are also related so that the method may be useful to all.
