Dr Kaila has done pioneering work in India on deep seismic soundings (DSS) technique. He was involved in the technical organization and management of this ambitious project. The DSS profiles in India with which he was concerned were laid in a variety of geological environments such as Cuddapahs and Dharwars in South India, the Deccan Traps in Maharashtra, the sedimentary basins in Gujarat and the Himalayas in the North. Dr Kaila interpreted the DSS data in terms of geological setting of the areas concerned and brought to light surface manifestations of the deep-seated structures.
