from older breads :
I was thinking the other day about those sismic waves, and can to this interesting idea.
Are W&W using these waves generated by some kind of phase-rumble machine?
Is it in combination with some satellites that monitor some areas on earth?
Follow my thinking? Some kind of sonar that could scan deep into earth's crust ?
Inventoring ALL underground cavities without any exception? So ((((((((((((nobody))))))))))) can hide his sorry ass when SHTF?
What ya think anons?
