Why are there almost no volcanoes in India?

Compared to other plate boundaries, the Himalaya and the rest of India seem awfully quiet when it comes to Volcanism. Sure there are a few small ones and some further north in Tibet, but compared to the Pacific Ring of Fire, Italy or the East African Rift, contemporary India seems almost dead in that regard.

That is because in the Himalayas, a continental plate is pushed under a continental plate, while in the ring of fire, oceanic plates are submerged. These are much heavier and sink deeper, thus melt easier. The composition of the material, including a lot of water, then makes the molten surface of the submerged oceanic plate rather 'volatile' (for the lack of a better word), so it ascends and forms volcanoes. Continental crust is pushed rather flat under the upper continental crust since both crusts have a rather light density, so the surface is not heated up as much and does not sear through the layers above.
