“The shaking was twice as strong as ‘Beast Quake.’
It absolutely doubled it,” she told CNN.
“The primary difference is the duration of shaking.

Cheering after a touchdown lasts for a couple seconds, but eventually, it dies down.
It’s much more random than a concert.
For [Swift], I collected about 10 hours of data where rhythm controlled the behavior.

The music, the speakers, the beat.
All that energy can drive into the ground and shake it.”
Naturally, fans who attended the iconic, not-quite-but-nearly earth-shattering performances shared videos of their experiences on social media.
One clip, posted by @liquorinourcocktails onTikTok,was captioned: “THE STADIUM WAS SHAKING.”
The video shows Swift singing “Cruel Summer,” while the crowd at Lumen Field happily screams along.
My phone was sitting on a ledge and just watch it shake."
Swift’s film is notably being distributed by AMC directly instead of by a major studio.
