Catastropic event is other name of pole shift theory.
A pole shift theory is a hypothesis based on geologic evidence that the physical north and south poles of Earth have not always been at their present-day locations; in other words, the axis of rotation had been "shifted". Pole shift theory is almost always discussed in the context of Earth, but other solar system bodies may have experienced axial reorientation during their existences.

Pole shift theories are not to be confused with plate tectonics, the well-accepted geological theory that the Earth's surface consists of solid plates which shift over a fluid asthenosphere. Poleshift theory also should not be confused with continental drift, the corollary to plate technonics which maintains that locations of the continents have moved slowly over the face of the earth[1], resulting in the gradual merging and breakup of continents and oceans over hundreds of millions of years.[2]

One early popular proponent of a pole shift theory was Charles Hapgood in his books The Earth's Shifting Crust (1958) (which includes a foreword by Albert Einstein) and Path of the Pole (1970). Hapgood speculated that the ice mass at one or both poles over-accumulates which destabilizes the earth's rotational balance, causing slippage of all or much of earth's outer crust around the earth's core, which retains its axial orientation. Based on his own research, he argued that each shift took approximately five thousand years, followed by 20 to 30 thousand year periods with no polar movements. Also, in his calculations, the area of movement never covered more than 40 degrees. His examples of recent locations for the North Pole include the Yukon Territory, Hudson Bay, and in the Atlantic Ocean between Iceland and Norway[3]

This is an example of slow pole shift motion, which displays the most minor alterations and no destruction. A more dramatic view assumes more rapid changes, with dramatic alterations of geography and localized areas of destruction due to earthquakes and tsunamis. Several recent books propose changes that take place in weeks, days, or even hours[4], resulting in a variety of doomsday scenarios.

Regardless of speed, the results of a shift occurring results in dramatic climate changes for most of the earth's surface as areas that were formally equatorial become temperate, and areas that were temperate become either more equatorial or more arctic.

Hapgood wrote to Canadian librarian, Rand Flem-Ath, encouraging him in his pursuit of scientific evidence to back Hapgood's claim and in his expansion of the theory. Flem-Ath published the results of this work in 1995 in "When the Sky Fell" co-written with his wife, Rose.

Other theories which are not dependent upon polar ice masses include:

A high-velocity asteroid or comet which hits Earth at such an angle that the lithosphere moves independent of the mantle
A high-velocity asteroid or comet which hits Earth at such an angle that the entire planet shifts axis.
An unusually magnetic celestial object which passes close enough to Earth to temporarily reorient the magnetic field, which then "drags" the lithosphere about a new axis of rotation. Eventually, the sun's magnetic field again determines the Earth's, after the intruding celestial object "returns" to a location it cannot influence Earth.
Perturbations of the topography of the core-mantle boundary, perhaps induced by differential core rotation and shift of its axial rotation vector, leading to CMB mass redistributions. See, e.g., Bowin.[5]
Mass redistributions in the mantle from mantle avalanches or other deformations. See, e.g., Ladbury, [6] and Steinberger and O'Connell.[7]
The field is plagued with non-scientific authors, offering a wide variety of things as evidence, including such things as psychic readings. Each of the various pole shift theories can be verified or debunked based on real evidence. Theosophic writer David Pratt[8] has put together an excellent comparison of scientific views regarding pole shift compared to those of Theosophy[9]

If you read through some of these articles you will see what happens (much better than I could).
