Tauristercus I find your presentation very informative and very professionally put forth, but possibly skewed to not really showing the real truth.
First of all your title was called "EARTHQUAKES: An analysis indicating increasing frequency and severity".
Then you produced two charts of two different sets of earthquake magnitudes, the 6s and the 7s; which by the way was excellent.
You only used a very short time frame which skewed your information from what the general public would have really taken as for a very long period of
time. You used the time frame of 1970 to the present in your excellent presentation. So... Your title would be accurate and your presentation would
be accurate if you would have made the title:
EARTHQUAKES: An analysis indicating increasing frequency and severity from the time period starting in 1970 to the present.
But somehow your presentation makes the reader think that you are trying to prove that your analysis indicates that earthquakes are increasing in
frequency and severity over a much larger time period; and that would be incorrect to lead the readers to believe that.
As Phage presented in his excellent chart that he created from USGS data that goes back further than 1970s, going back to 1900 it shows a true
representation of earthquake activity for earthquakes in the magnitude 7 range. His short but accurate presentation actually debunks your
presentation over the 1900 to present time period.
Should you be able to present a chart similar to Phage's over the same time period (1900 to present) showing that the magnitude 6 range of
earthquakes increased over that complete period of time (1900 to present), then your presentation would look better; but I doubt that you would be
able to pull up a chart of the 6s from 1900 to present to make your otherwise excellent presentation look less skewed. I suspect that the 6s from
1900 to present look as though there is no real increase in frequency and severity.
On the other hand... people are creating earthquakes that people before our time never created; simply because of the mining, extraction of fluids
like oil and building of huge dams.
I believe you are trying to make a presentaton to show that some of what is occurring in the realm of earthquakes is from mankind creating earthquakes
and that man made earthquakes are becoming more frequent and dangerous.
It's the far future that mankind should be taking care of. In the far future there will be terrible earthquakes because of what mankind is currently
doing. Terrible earthquakes of greater frequency will occur in the far future when all of us have passed on because mankind did not plug all of the
old useless oil wells from the very bottom to the top; instead 20 or so feet of pipe is plugged near the surface.
There are many oil fields in areas with aquifers that have oil pipes extending up through the aquifer fields. Here in this area the top of the
aquifers are only down about 10 to 20 feet. Old iron oil well pipes extend down through the bed of water which is 100 to 200 feet deep in many
places. When these old abandoned oil well pipes finally rust through, a hundred to hundreds of years from now, the water from the aquifers will flow
down inside of the empty pipes and the pressure alone from a water column extending down over 2000 feet and striking the rock formation far below will
cause terrible earthquakes in the regions of the aquifers and other regions at great distances.
All old oil well pipes need to be filled from the top to the bottom to stop this catastrophe of the future from happening. This is a catastrophe that
mankind cannot believe that is waiting to occur. The pressure from a column of water over 2000 feet in depth will be more than enough to create some
serious pressure and some serious earthquakes, especially since mankind won't be able to stop it once it starts, or to be able to figure out which
pipe is causing it. The problem is, is that there are 10s of thousands of these pipes all over the world, and they all need to be filled from top to
bottom when production has ceased or when the well is abandoned.
I didn't mean to change direction of your topic here in the latter paragraphs, but I wanted people to realize that there are going to be countless
catastropic earthquakes in the far future if mankind doesn't use an ounce of prevention now. I make all of these latter acknowledgements due to my
knowledge of how to detect earthquakes of all magnitudes before they strike and how to forecast them accurately anywhere in the world.
During my decades of detecting earthquakes before they have struck, due to all magnitudes of terrestrial originated earthquakes having precursor
pulses that are detectable due to rocks releasing energy and radiation, and the fact that my equipment shows mankinds earthquakes as well as Earths
natural earthquakes; I was able to postulate that far in the future countless man made massive earthquakes will strike if old oil well pipes aren't
plugged from top to bottom instead of 10 to 20 feet of it at the top.
