Dispersion of Rayleigh waves along several paths in the Indian Ocean have been studied by means of records from Shillong. From the observed group velocity data it was found that the average thickness of the crust under the Indian Ocean is about 5.10 km. It was also found that the bottom of the Indian Ocean is likely to be covered, by a series of ridges.
