The Broach earthquake has been studied in detail. Fault plane solution using first motion P-data from 5 arrays and 51 ether stations indicates a possible tectonic royement along the NE striking Aravalli fault. Modified Cohens cepstral technique when applied to three teleseismic array records gives a focal depth of 21 km for the event, which coincides with the value obtained as a convergent solution to hypocenter by an iterative procedure using P arrival times at 23 well distributed stations in the distance range 20° to 88°.
