When plate movement causes rocks to break it is call an earthquake.
Orogenesis
The weight of the rocks above the mantle results in high pressure.
Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.
There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.
Fault-block mountains form due to divergent boundary plates.

The magnitude 9.0 earthquake (originally reported as 8.9) on Friday, March 11, 2011 happened near the east coast of Honshu, Japan. According to USGS, the epicenter of the quake was reported to be 129 kilometers (80 miles) off the east coast of the Oshika Peninsula, TÅhoku near Sendai.
In was reported that the earthquake created tsunami waves of up to 10 meters (33 ft) that struck Japan, with smaller waves in many other countries, with a significant surge and damage as far away as Chile, on the opposite side of the world from Japan. In Japan, the waves are reported to have traveled up to 10 kilometers (6 miles) inland.
