Abstract

A computer programme has been developed for the epicentral determination on routine basis using p and S phases. In addition to teleseismic phases, provision has been kept for including all or any of the near earthquake phases, namely Pn, P* and Pg as well as Sn, S*and Sg* Solutions can be obtained at present for focal depths ranging from zero to 280 km within the eplcentral distance of 90 degrees. The programme incorporates built-in consistency checks to deal with errors in the data and so discards outright or reduces the effective weightage in the computation of the concerned observations not falling within acceptable limits.

 

The results agree fairly well with the bulletins of U .S. Geological Survey, International Seismological Centre, U.K. and USSR.
