Ok I think I found a legitimate video showing a bridge collapse due to resonance.
The bridge out of the blue started bending so much, and this was caused by AIR frequency.
This should be the same with what happened in Shenzhen. No earthquakes, no high winds, nothing. Just started shaking without any obvious reason
