As it stands now, when do the Zetas say the main earth changes will be completed.
We have described the steps to the pole shift, which are:
After the shift, the melting poles and glaciers and rise of the oceans due to heat generated by the shifting crust will cause the oceans to rise to 675 feet above the current sea level. Aftershocks from the magnitude 9 quakes that occurred during the pole shift will continue for hundreds of years.
