It's called the "Great American Shakeout"... and no, it's not about Taylor Swift's hit song “Shake it off”.
It's a nationwide earthquake drill meant to help everyone practice and prepare what to do during an earthquake. Kind of like a fire drill, which I’m sure most of you have practiced.
In Oregon, more than a half-million people signed up to take part in the worldwide drill.
Elishah Oesch has more.
