ah I was told I could eyeball it when comparing it to what actual earthquakes are capable of in that page and the charts provided, I don't know how to prove the plates were moving but its said numerous times to be earthquakes with a character even looking at the seismic energy with a device and they've been shown to affect things in the distance like the water tower falling and making stuff shake even on the kent farm and the other destruction in the clip
I'd also suggest you gif the earthquake stuff since there's always a chance of the CW/WB randomly remembering the show exists and taking down a bunch of clips
