In December 2004, an earthquake shook the East, spawning tsunamis and causing devastating surface damage. Beneath the surface, the earthquake was also responsible for altering Earth's gravitational fields.¹ Although very slight, orbiting satellites detected the nuances through deviations in the Earth's crust and alterations of their GPS configuration. Such a change is not without precedent; gravitational changes are attributable to changing densities in the Earth's composition, primarily from PGR (Post Glacial Rebound) following the last Ice Age.

¹ Our understanding of gravity comes from Newton's Laws of Motion, formulated after the legendary apple fell on Sir Isaac's head. The attractive force is governed by the relationship of mass, distance and the gravitational constant.
