In March 2012, a devastating F4 tornado struck the town of Henryville, Indiana, leaving behind a path of destruction that shocked the nation. One of the most dramatic moments of this event was captured by a security camera inside the Henryville High School gymnasium, offering a rare and terrifying glimpse into the raw power of nature.
The footage shows the gym being violently ripped apart within seconds as the tornado tears through the building. Moments later, viewers can see the vacuum effect created by the tornado as it moves out of the structure — a powerful reminder of the intense pressure changes occurring within such violent storms.
This tornado was part of a larger outbreak system that produced dozens of destructive twisters across the Midwest, claiming lives and causing extensive damage to homes, schools, and infrastructure. The Henryville F4 tornado remains one of the most infamous and well-documented tornadoes in modern U.S. history.
Even years later, the video continues to serve as a sobering reminder of why tornado preparedness, safety planning, and early warning systems are essential in tornado-prone regions.
