More than 200,000 people in Illinois will duck under their desks for an earthquake drill this morning.
Dozens of Chicago-area schools, businesses and institutions pretended the ground was shaking during a Thursday drill.
As part of the "Great Central U.S Shakeout," an earthquake drill was held at 10:15 a.m. in 11 states across the country, including Illinois.
Organizers hope the drill will raise awareness about a potential disaster, even though earthquakes are extremely unlikely in Illinois.
More than 200,000 people in the state were expected to participate by ducking under their desks to protect themselves from falling objects.
