High-frequency three-component array data are used to study the P and S coda produced by local earthquakes. The data are displayed as broadband bearing-time records which allow us to examine a complete time history of the propagation directions and arrival times of direct and scattered phases crossing the array. This visualization technique is used to examine the wavefield on two scale lengths using two sub-arrays of sensors. Results suggest that P coda is dominated by P energy propagating sub-parallel to the direct P arrival. The S coda propagates in all directions and appears to be composed predominantly of S and/or surface wave energy. Significantly more S coda appears on the smaller scale length sub-array relative to the larger scale array suggesting that much of the S coda remains coherent for only very short distances. ¿ American Geophysical Union 1993
