Japan earthquake demonstrates the limits—and power—of science 2011-03-11T18:45:08.260Z The tectonics in this part of the world are, of course, well-understood. Extraordinary earthquake 2011-03-11T09:00:34Z “All of the pieces suddenly made sense if you believed plate tectonics was going on,” said Larry D. Brown, a professor of geological sciences at Cornell who was a former student of Dr. Oliver. Jack Oliver, Who Proved Continental Drift, Dies at 87 2011-01-12T05:27:49Z The term "tectonics" refers to forces that cause movements and deformation of the Earth's plates. Wind Can Keep Mountains From Growing 2011-03-30T18:57:00Z Such images, showing underlying sediments, rocks, faults and other structures, became critical to forming the modern theory of plate tectonics and understanding earthquake hazards in many places.
