Discrimination of Temporally Overlapping Seismic Events

Abstract

ROUTINE digital processing of seismic events recorded on analogue magnetic tape at the Yellowknife seismic array, Canada, is being carried out in Ottawa with the aid of a computer. The array is of the UKAEA pattern and has been described by Manchee and Somers¹. Processing methods have been described by Weichert et al.². Although no attempt is being made to process every event that is received, a large enough sample is selected from each month's recording to enable a library of third zone events to be accumulated on digital tape. Sometimes, as in the present instance, a particular event is of more than passing interest.
