The "Great Oregon Shakeout" happened at exactly 10:18 a.m.
Students at North Bay Elementary took part in their own form of earthquake drill.
To keep the kids engaged, Principal Reeves made it a fun activity, with added sound effects.
Although there were some giggles, fourth-grade teacher Julie Johnson made sure the students realized the importance of practicing for an earthquake.
"It was a lot of fun and it was very cool. The kids were really excited. We talked about it this morning because it was the largest earthquake drill ever done and so that kind of got them some motivation. Anytime you do something that's the largest, kids get excited about it," Johnson said.
Experts predict Oregon is due for a large earthquake in the coming years.
