Abstract: In this paper the recent tectonic stress of the Himalaya mountains arc and its vicinities is analysed, basig on the data both from the earthquake foci mechanism and the features of the geologic structure of these regions.Therefore three main conclusions are drawn as follows:1. In the lower part of the lithosphere beneath these regions, the axis of the principle compressional stress is in the NNE-SSW direction, that is probably caused by the movement of the Indian Plate towards north.2. In the upper part of the lithosphere, the axis of the principle compressional stress is perpendicular to the strike in the outer part of the are and parallel to the strike in the inner part, that is possibly controlled by the bending mechanism in the course of formation of arc structure.3. The Himalaya arc, the Burma arc and the Baluchistan arc are resulted from the layergliding caused by the underthrusting of the drifting northward Indian Plate.
