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 ...
Based on paleointensity data for the last 800,000 years, [56] the magnetopause is still estimated to have been at about three Earth radii during the Brunhes–Matuyama reversal. [48] Even if the internal magnetic field did disappear, the solar wind can induce a magnetic field in the Earth's ionosphere sufficient to shield the surface from ...
The North magnetic pole is approximately 965 kilometres (600 mi) from the geographic North Pole. The pole drifts considerably each day, which results in a change of 5-60 km per year. The speed of the change was around 10 km/year for the majority of the 20th century, then increased in the 1990s to over 50 km/year, but slowed down slightly after ...
The Brunhes–Matuyama reversal, named after Bernard Brunhes and Motonori Matuyama, was a geologic event, approximately 781,000 years ago, when the Earth's magnetic field last underwent reversal. [ 1 ] [ 2 ] Estimations vary as to the abruptness of the reversal.
The shift “was unprecedented as far as the records we have,” he added. Around 2015, the drift slowed to about 21.7 miles (35 kilometers) per year. The rapid deceleration was also unprecedented ...

Then, Earth would be devastated by a series of magnitude 9.8 earthquakes, Earth's magnetic pole would shift by 30 degrees, the United States would be split in half, and Barack Obama would be elected president for an unconstitutional third term. [46] He predicted that the seven-year Great Tribulation would begin on October 15. [47]
The Earth's Magnetic North Pole is actually considered the "south pole" in terms of a typical magnet, meaning that the north pole of a magnet would be attracted to the Earth's Magnetic North Pole. [2] The north magnetic pole moves over time according to magnetic changes and flux lobe elongation [3] in the Earth's outer core. [4]
