The pole shift itself will be magnitude 9 worldwide. Aftershocks as large as magnitude 8 or even 9 can be anticipated to be strongest in those parts of the world where extreme subduction has occurred, as thus the weight of a land plate will be pressing down and some rock strata snapping as it breaks under this pressure. The shear cliff at Yosemite is an example of such rock breakage. This would be true, after the pole shift, for New Zealand and eastern Australia, the region of Tibet, Japan, Kamchatka and the Aleutian Islands, a few hundred miles into the West Coast of the Americas (both north and south America). In areas experiencing stretch, the land will likewise be restless for some time, but this will be in the form of jiggling when some lingering support gives way and allows a portion of a land plate to drop further. Where it is assumed that the new course of a river has been established, there may be days of jiggling with the result that the river has round a new course, for instance. Construction in all such regions should be of light materials designed to be highly flexible. The ancient Japanese perfected these construction techniques, which could be studied. Items that can shatter should always be on the floor where they can roll, rather than drop. For the Japanese, this often included human beings, who lived and rested close to the floor for just such reasons.
