Application of improved frequency-time analysis has made it possible to investigate Rayleigh wave group velocity dispersion in Southern Asia for periods extending to several minutes. WWSSN data recorded at New Delhi, India, and Shirza, Iran, which lie approximately on a great circle path from an epicenter in the New Hebrides, have been analysed. Preliminary results indicate that inter-station group velocities between these two stations, obtained by means of modified cross-correlation, resemble results previously reported for shield regions.
