Czech earthquake swarm = “induced seismicity” (man made quakes) = building an underground base?

No one has stated the “cause” of the rumored 10,000 earthquakes in the Czech republic….
Now we see in this video, an earthquake swarm 100% identified in the Czech republic.. but clearly you can see this swarm is NOT NATURAL ! .. the grid pattern .. a pattern of “blasts” from underground?
I say underground base.. because at the end of this video, he shows the terrain in question..
These quakes are occurring UNDERNEATH A TOWN ! Either that or a secret mining project that was given the OK to cause 4.0 earthquakes …CONTINUE
