I have discovered something very important in regards to the worlds largest ever recorded earthquakes.
There is a relation between large earthquakes location AND their depth.
(article has been updated with new graphics to show the relation in an animated GIF)
If you look at the worlds largest earthquakes plotted on Earthquake3D, you can see something rather odd… notice how all the large earthquakes span a circumference very similar?
If you connect the dots of these largest earthquake epicenters, we almost see an off center line of longitude.
Also, more importantly make note of the DEPTH of all these large earthquakes!
This cannot be just coincidence. Almost every single large earthquake this past century occurred at or around the 30km depth.
This includes the March 2011 Japan mega-earthquake (30km deep), and the 2004 Sumatra Indonesia mega-earthquake (33km deep).
It appears that IF there is a large earthquake, then the depth of that large earthquake will be in the 30km range.
This is the full list , ironically making news rounds TODAY April 25, 2015:
