Mode and Mechanism
According to the AECOM report commissioned by TVA and released June 25, 2009, failure occurred due to a variety of causes, primarily due to liquefaction of layers of "slimes" and other water-saturated materials deep within the growing ash pile. Collapse occurred over the course of approximately one hour in consecutive waves of breaking away and sliding.

Famous quotes containing the words mode and/or mechanism:
“The mode of clearing and planting is to fell the trees, and burn once what will burn, then cut them up into suitable lengths, roll into heaps, and burn again; then, with a hoe, plant potatoes where you can come at the ground between the stumps and charred logs; for a first crop the ashes suffice for manure, and no hoeing being necessary the first year. In the fall, cut, roll, and burn again, and so on, till the land is cleared; and soon it is ready for grain, and to be laid down.”
—Henry David Thoreau (1817–1862)
“The law isn’t justice. It’s a very imperfect mechanism. If you press exactly the right buttons and are also lucky, justice may show up in the answer. A mechanism is all the law was ever intended to be.”
—Raymond Chandler (1888–1959)
