What are the relative importances of diastropism and volcanism in the production of earthquakes?
Large-scale deformation of the Earth's http://www.answers.com/topic/crust by natural processes, which leads to the formation of continents and ocean basins, mountain systems and rift valleys, and other features by mechanisms such as lithospheric plate movement (seehttp://www.answers.com/topic/plate-tectonics), volcanic loading, or folding. The study of diastrophism, or tectonic processes, is the central unifying principle in modern geology and geophysics. Kalra
