Exactly, their silence is proof in itself.

A big tell for me with these quakes is that there is no visible damage. These are massive quakes that would shred cities. Some are triggering volcanic activity warnings, some are triggering typhoon warnings. But we see neither.

The fact that they are all at the same depth is noteworthy. Even if say the explosions all happen at a similar depth, but the seismic monitors are reading them as lower? Or that a downward blast triggers the censors at a much lower depth? Not really sure on that one.
