The big news about Earth’s axial shift, caused by the Chilean earthquake, sounded amazing. The quake not only shifted the axis, but it also shifted the length of a day on Earth. But the “normal” shifts are so much greater.
Since Earth is not a perfect sphere, it has axial shifts all of the time to try to find spherical equilibrium. How do the big earthquakes affect things? “The Chilean quake shifted enough material to change the mass balance of our entire planet,” said Richard Gross, JPL. The shift in material caused the wobble in Earth’s axis to increase by about three inches. The wobble changes as Earth’s mass progresses toward being a perfect sphere. A normal axial shift is about 10 centimeters per year, but the 8.8 magnitude quake hurried it along this year.
A greater time shift was also caused by the quake. The Earth day was shortened by about 1.26 microseconds within 24 hours, a negligible amount. Winds and tides can affect the rotation of Earth hundreds of times more than an earthquake can, but we still do not notice the change.
As Earth rotates, wobbles, shifts, and revolves, changes are always going on. Sometimes we notice them, sometimes not.

I work at a Turkish University, but the earth shift idea and the data I have is conceptually too big for colleagues to handle. My job coonnects me to Marine science and technology and to maritime affairs such as navigation. The data is in part geographical and in part mathematical
However it belongs essentially to studies of the 1330s-copied Portolan “navigational” charts made by Opicinus de Canestris in Papal Avignon. The 44 charts belong to the London University Warburg Institute.
I have been doing computer analysis and conceptual restoration of these Codex Palatinus Latinus 1993 items for the past 7 years. The 44 relevant items depict maps and calculation instruments. Evidence suggests they originated in Egypt at a time following the connection of the Balack and Aegean Seas, perhaps 5,000 years ago.
When stripped of their purely 1330s grafiti they present very radical geometric data of a remarkably high standard. When I place key items upon an appropriate world map they show clearly, compellingly and indisputably a 180 degree belt of our planet when it had a radically different axis. The belt is fixed by geometry and by placing scans of the Mediterranean and NE Atlantic coastlines on a world Mercator chart.
This is clearly evidence of great importance. I need to consult somebody who can handle it. Please get back to me.
