Web1 INTRODUCTION. Coda waves have been analysed as scattered waves by random small-scale heterogeneities distributed in the solid Earth since the pioneering work of Aki & Chouet ().Coda waves are thought as incoherent scattered waves and the spatial distribution of their intensity at a late lapse time becomes almost uniform and isotropic. http://eodg.atm.ox.ac.uk/user/grainger/research/book/protected/Chapter5.pdf
