Non-linear stochastic models for seismic events with applications in event identification

A special class of pth-order autoregressive stochastic models is proposed for seismic records of e%plosions and earthquakes. These models are based on deterministic formulations proposed by Haskell, Von Seggern & Blandford and Aki. Statistical properties of the estimation procedure are derived and the model applied to seismic records of P waves. The method is shown to have applications in depth and reflection parameter estimation and in event discrimination.
