Yes, we have known of man-made earthquakes for some time. There have been a steady stream of them done at regular intervals in west Texas and northeast Texas thanks to injection wells being used to increase the water table in order to force more oil up the extraction wells. In these cases, the water acts as a lubricant and a *jack* (hydrostatic pressure will force the rock apart a minute amount, allowing more movement). These earthquakes are normally very mild, and usually never exceed about 2 on the richter scale, if that.
Indeed, Nikola Tesla did experiment with numerous apparatus for setting up complimentary harmonic resonation in various objects, and finally in the earth itself. Tesla himself wrote in his papers that he had constructed a device, man portable, that when attached to a building could set up a harmonic resonance great enough to cause structural damage, and he apparently tested it on a building under construction. There is apparently some truth to this claim as the building was documented to have been fairly severely damaged.
Tesla in his papers describes methods of setting up standing and complimentary harmonic resonance in the earths crust, resulting in earth movements that could be targetted across the globe. He did theorize that given the proper tuning and power input it would be possible to reach a resonance that would "split the world into pieces"
It is known that seismic activity is often associated with large scale emissions from HAARP. It has been theorized that HAARP has been actively used to generate seismic events on different parts of the planet, thereby "weaponizing" earth movements.
I often take to correlating seismic activity to recorded HAARP transmissions from Gakona.
Considering that the military has only had about 60+ years to go through Teslas papers and develope his concepts into a workable technology, this is not at all surprising.
