Travis Scott bringing out Ye during his concert in Rome caused vibrations so intense that locals feared it was an earthquake.
“Italy’s fire service confirmed to CNN that it received ‘hundreds of calls’ from concerned residents who feared there had been an earthquake in the Italian capital. [...]
The movement turned out to be a result of tens of thousands of people jumping up and down to the music, especially when Scott introduced a surprise guest: Kanye West.” (via CNN)
The vibrations from the crowd’s jumping were calculated to be equivalent to a magnitude 1.3 earthquake by seismologist Giovanni Diaferia.
