We present a short review on the seismicity and crustmantle structure of the Indian subcontinent highlighting the major findings of the work done during the last few decades. Seismicity pattern and seismic power-law characteristics and the velocity structures studied by different techniques (seismic tomography, receiver function etc.) for various tectonic zones of the Indian subcontinent are summarized. In addition, some results on seismic anisotropy, seismic attenuation and ambient noise analyses are abridged. The results though provide some insight into the seismicity, triggered earthquakes, crust - mantle velocity and lithospheric structures for the continental shield region, oceanic intrapale, collision and subduction zones of the Indian subcontinent, highresolution sub-surface images need to be studied using high quality denser seismological network data with integrated multi-geophysical, satellite and other imagery data in future study.
