English: Diagram of the dissymmetrical gravity field of the Earth, walking around in nine steps. The image has been composed from the GRACE satellite mission's results. The coloured surface depicts the level of varying altitudes where the gravitational pull is exactly the same. The geometric proportion is extremely exaggregated for better perceptibility. The purple, highest areas show some higher gravity of greater mass concentrations under the ground, the anomality value is cca. +60 mGal (0.0061%). If you make a high accuracy weight measurement here at a distance from the geometric center of Earth then you receive higher value than at the cyan area, at the same geometric altitude. Cyan indicates deviation nearly –70 mGal.
