Logarithmic scales don't work like that. An earthquake of magnitude 8.5 actually releases about 5.6 times more energy than an 8.0 earthquake. For an 8.1 earthquake the factor is about 1.4.
By the way, there are treatments available for paranoid/delusional disorders.
Originally posted by KostenuikMore points? What do you mean by points?
Well you want to study the 0.05% of largest pigs, so shouldn't the largest of the large get more points in their favour? If 1 whole point is equal to 31.6 times the energy then it would take that many pigs at the lowest level to equal the top one.
The scale being logarithmic or not is irrelevant, what matters is the underlying distribution. They would still be the top 0.05% whether you rescale them or not.

I haven't looked at the amount of quakes that have happened in each decade, as some are smaller then others, but the combined energy value of each decade to see where changes in total energy of the top x percent have occured from year to year... decade to decade.

I'm not sure what you mean by underlying distribution.

Thanks flex. Very similar results.
It all points to it being simply the result of randomness in a small sample.

It still shows the similar trends as the 1910's, 70's, 80's & 90's all low. and more importantly around the sixties and begining of this century extremely high.
I'm not sure the amount of measuring stations would make a difference to the largest of quakes as multiple stations around the earth measure the individual quake to plot it's location and size. In 1931 there were 350 measuring stations compared to around 8000 today so the smaller quakes would definetly be faulty but large one's one would think would still be sound. http://earthquake.usgs.gov/learn/topics/increase_in_earthquakes.php

So x years pressure builds up on the earth's plates but doesnt release and then all of a sudden it releases it's energy and gets it out of the way after which point there isn't any plates liable to cause any quakes and the cycle starts anew. Exactly like an earthquake in slow motion but over a decade or more in time and then calm. So what I am saying is if you are in the middle of an outbreak(decade) of some of the largest earthquakes... the possibilities that more will happen is high. Also as you have pointed out... the after-effects will not be more earthquakes but calm as those plates have used up all their energies. I do not see that as random.
