I picked up on a post from yesterday and went to the official site above.
I read that the D.U.M.B.S are at a consistent 10km below the surface around the world.
Now the USGS measuring system shown above plotted 37 earthquakes of 2.5 magnitude or more in the last 24 hours at depths between 1.9km and 501km below the surface. Assuming the equipment records to a rounded up level of 100m or 0.1km that would mean the equipment can plot at over 5000 measurement points.
The earth being a natural phenomenon will not offer up its earthquakes to the recording system to a scientifically precise 10km.
Yet 10 different earthquakes around the world in the last 24 hours were. Recorded at the plotting point of 10km. 25% of earthquakes . That looks like a statistical impossibility.
It’s in the link in the post above the United States Geological Survey.
About the 10km depth recorded.That is a figure used by them when other info isn’t known.
Here is the interesting thing.
If we start at 2.0mag the increases to 5.0mag mean that 5.0 is 1000 times more powerful.
Most of these 10.0km deep defaults are above 4.5. These rate as significant recordings but not earth shattering . The range recorded in recent days ( you can go back and custom set) are consistent with a recoding of 4.5 to 5 ( 1.1 to 10 is recordable).
Again allowing for the Earth being a natural environment ( slight discrepancies in geology)the plausible explanation could be that “ the quake” was a man made event using a man made force.
Alternatively you would see recordings across the scale like with the earthquakes that are more likely to be natural events.
The equipment can monitor a 4.5 mag EQ at 1km or 500km below surface it’s still a 4.5mag EQ.
Awesome, I forgot to expand your post.
Thanks for clarifying and the additional info!
