[66] By examining subduction zone geometry and comparing the degree of curvature of the subducting plates in great historical earthquakes such as the 2004 Sumatra-Andaman and the 2011 Thoku earthquake, it was determined that the magnitude of earthquakes in subduction zones is inversely proportional to the degree of the fault's curvature, meaning that "the flatter the contact between the two plates, the more likely it is that mega-earthquakes will occur."[67]. ) E Required Prerequisites: (ECE421C, 421XS, ME432C or 432XS) and (ECE424*C or 424XS). Here the plate shallows slightly before plunging downwards, as a consequence of the rigidity of the plate. {\textstyle a_{n}=\bigtriangledown ^{2}f(\theta ^{*})^{-1}/n} Since the Earth's circumference has not changed over geologic time, Hess concluded that older seafloor has to be consumed somewhere else, and suggested that this process takes place at oceanic trenches, where the crust would be melted and recycled in the Earth's mantle. For the purpose of checking the descent condition in actual calculations, it may be more convenient to write the inequality of Eq.

The concept of subduction would play a role in the development of the plate tectonics theory.[75]. If the quadratic step exceeds the trust radius and a minimum is sought, the step is reduced in length to the trust radius by searching for a minimum of the quadratic function on the sphere having the trust radius, as discussed by Jrgensen [.

A comma separated list of options can follow the coordinate label, enclosed in parentheses. [ Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. [73] The ancient magnesium-rich rocks mean that Earth's mantle was once hotter, but not that subduction conditions were hotter. In linear algebra and numerical analysis, a preconditioner of a matrix is a matrix such that has a smaller condition number than .It is also common to call = the preconditioner, rather than , since itself is rarely explicitly available. 1 For a quadratic cost function it is possible to scale the design variables such that the condition number of the Hessian matrix with respect to the new design variables, is unity (the condition number of a matrix is calculated as the ratio of the largest to the smallest eigenvalues of the matrix).
