Scattering of seismic waves by lithospheric heterogeneities produces seismic coda which typically look random. Consequently stochastic modelling methods are usually applied to these coda [1–6]. Here, we introduce a technique, based on previous work [7], for evaluating the predictability of time‐series data as an indicator of underlying determinism. When analyzed using this method both earthquake and explosive source seismic coda display strong short term predictability which is not consistent with a random generation mechanism.
