The study included data from 1993 through 2010, and showed that the pumping of as much as 2,150 gigatons of groundwater has caused a change in the Earth’s tilt of roughly 31.5 inches. The ...
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...

From 1993 to 2010, the earth is believed to have tilted 31.5 inches east, according to the study, which was published by Geophysical Research Letters. This is because of how much groundwater was ...
In Maps of the Ancient Sea Kings (1966) and The Path of the Pole (1970), Hapgood proposed the hypothesis that the Earth's axis has shifted numerous times during geological history. [2] The Path of the Pole was meant as a replacement for The Earth's Shifting Crust after corrections were suggested to him.
Cases of true polar wander have occurred several times in the course of the Earth's history. [1] [2] It has been suggested that east Asia moved south due to true polar wander by 25° between about 174 and 157 million years ago. [3] Mars, Europa, and Enceladus are also believed to have undergone true pole wander, in the case of Europa by 80°. [4]
Scientists have long understood that that can accelerate or slow the planet’s rotation — a trend that can shift over 10- to 20-year intervals. Right now, the core is temporarily causing the ...
Due to the very slow pole motion of the Earth, the Celestial Ephemeris Pole (CEP, or celestial pole) does not stay still on the surface of the Earth.The Celestial Ephemeris Pole is calculated from observation data, and is averaged, so it differs from the instantaneous rotation axis by quasi-diurnal terms, which are as small as under 0.01" (see [6]).
