The original post was by me some weeks ago, this was the
link.
There are many depth numbers - pinpointed quite accurately, but the depth of 10 crops up very regularly.
I emailed the Seismical Research place in UK to query this, and did not receive a reply.
A lot of these depth of 10 areas are in 'war zones', and also there were a number in the North West Pacific. Too many coincidences?
