A strong Magnitude 6.8 earthquake has just taken place 1528.1km southeast of East London, South Africa. It took place at a shallow depth of only 10km. Problem is, this is the approximate "Antipode" for the Cascadia Subduction Zone off Vancouver, Seattle, and much of northern California.
There is a school of thought that holds when a major earthquake takes place on one side of the world, it directly affects its "antipode" which is the precise location on the exact opposite side of the planet.
According to the Antipode map, A Quake in this area off South Africa has its Antipode around Vancouver, BC, CANADA. Since the antipode effect can vary from precise, the entire Cascadia Subduction Zone is now in the crosshairs:
Quite often, a major earthquake on one side of the planet causes another one, afterwards, very near the exact opposite side of the planet. If that holds true, the Cascadia Subduction Zone of the US West Coast, could be in for quite a ride.
UPDATE 4:01 PM EDT --
A Magnitude 5.6 earthquake has just taken place in the area of the Cascadia Subduction Zone, as mentioned possible in the story above!
