Fig. 9: The Indian plate is too thick and its density is too low for it to be subducted beneath the Asian plate. The result is a collision, causing sea floor sediments to be pushed up about six miles, uplifting the Tibetan Plateau, a region the size of Alaska, to an average elevation of over 16,000 feet and causing many earthquakes. Higher magnitude earthquakes occur too often in this region.
