The analysis of more than 386,000 earthquakes between 1973 and 2007 recorded on the US Geological Survey database proved that the global annual energy of earthquakes on Earth began increasing very fast since 1990.

Or maybe the USGS has deployed more sensitive seismographs between 1973 and 2007, and adding up the total energy of all the detected earthquakes keeps on increasing, because we are detecting many more small earthquakes today than we could in 1973.

Maybe...but have you also considered all the extra siesmic readings due to tunneling by the aliens, as they enlarge their UFO bases under the Himalayas, Antarctica, Mount Shasta...?

We need to get Noory's & Art Bell's opinions on this.

“Or maybe the USGS has deployed more sensitive seismographs between 1973 and 2007”

That’s what I’m thinking too. (And more of them). It would be interesting to see if there is a variation in number of earthquakes, intensities, etc. over time. I’m a firm believer in Catastrophism in the life of this earth and obviously we have had some very violent times over our 3.5 billion years. I wonder if there is a cyclical nature to earthquakes (related to magma motion, etc.) like there is to the solar sunspot cycles and all sorts of other things that happen in a cyclical nature.

I would imagine that there is, but it might be such a long period that we don’t have enough good data on it yet. Not sure how it would help. (”Announcement - for the next 200 years we may have increased sesimic activity. Try to stay near doorways and always keep a hand ready to catch Grandma Edna’s urn on the fireplace mantle”.)
