        A new story based on a fascinating scientific paper is making headlines all over the news: the slowing rotation of the Earth may be causing synchronized earthquakes. Moreover, as the Earth's. "Earth's rotation changes all the time as a result of not only earthquakes, but also the much larger effects of changes in atmospheric winds and oceanic currents," he said. "Over the course of a year, the length of the day increases and decreases by about a millisecond, or about times larger than the change caused by the Japanese earthquake.

        Now, scientists believe a slowdown of the Earth's rotation is the link to an observed cyclical increase in earthquakes. To start, the research team of geologists analyzed every earthquake to occur Author: Trevor Nace. A more precise measure of earthquake magnitude than the Richter scale that is derived from the amount of displacement that occurs along a fault zone. Primary (P) Waves A type of seismic wave that involves alternating compression and expansion of the .

        The earthquake that created the huge tsunami also changed the Earth's rotation. Dr. Benjamin Fong Chao, of NASA's Goddard Space Flight Center, Greenbelt, Md. and Dr. Richard Gross of NASA's Jet Propulsion Laboratory, Pasadena, Calif. said all earthquakes have some affect on Earth's rotation. This book explains concepts in behaviour of buildings during earthquakes. The book dwells on basic concepts in earthquake resistant design of buildings, first describes these at a conceptual level and then articulates further with numerical examples. It is an attempt to respond to some of.

The static displacement field generated by an earthquake redistributes the Earth’s mass and consequently causes the Earth’s rotation and global gravitational field to change. Proponents of the Earth Crustal Displacement Theory believe that the North and South Poles have not always been in their present location.

Instead, the Earth’s axis of rotation changes in a predictable fashion which may have changed the course of human history. The theory was first put forth by Joseph Adhemar in he believed that thick ice accumulated.

This paper adopts the elastic dislocation to compute the co-seismic polar motion and variation in length of day (LOD) caused by. Perhaps, as it is underlined in preface of a book, still the majority believes that such rotation motions are not related to inner rotations but are directly related to rotation in the displacement field which may reach much higher magnitudes in materials with an internal structure than in homogenous layers; considering damages in the high Cited by: 3.

Richard Gross, of NASA's Jet Propulsion Laboratory, calculates that last week's earthquake off Japan's coast may have shortened the length of Earth's days by about microseconds and shifted. An observational test is made of the hypothesis that large earthquakes excite the Chandler wobble and produce the observed secular polar shift.

This hypothesis was advanced on the basis of theoretical calculations using the elasticity theory of dislocations to represent displacement fields and earthquake statistics to estimate cumulative by:.

In his books The Earth's Shifting Crust () (which includes a foreword by Albert Einstein) and Path of the Pole (), Hapgood speculated that accumulated polar ice mass destabilizes the Earth's rotation, causing crustal displacement but not disturbing the Earth's axial orientation. Hapgood argued that shifts (of no more than 40 degrees) occurred about every 5, years.

During an earthquake, the mass distribution in the Earth’s crust changes. This changes the Earth’s moment of inertia, which is the sum of the moments of inertia of each point. The moment of inertia of a point mass is the product of its mass and the square of its distance to the axis of rotation.Earth Crust Displacement "In Charles Hapgood suggested in his book The Earth's Shifting Crust that the Earth's crust had undergone repeated displacements and that the geological concepts of continental drift and sea-floor spreading owed their secondary livelihoods to the primary nature of crustal shift.

According to Hapgood, crustal shift was made possible by a .
