The Indian plate is moving northward at a rate of about 47 mm per year, driving into Eurasia, which is moving to the northeast at about 20 mm per year. This causes uplift along the border between the two plates, creating the Himalayas, the Tibetan Plateaux, and the mountains of central Asia. It also causes India to compress, getting about 4 mm shorter along its north-south access each year, and leads to regular Earthquakes on both tectonic plates.

The most recent major Earthquake was in September 2011, on the border between Sikkim and Nepal, which measured 6.9 on the Richter Scale, and killed 111 people, mostly in Sikkim. In 2001 an Earthquake in Gujarat measuring 7.7 on the Richter Scale killed over 20 000 people.
