We stumbled upon this awesome visual of tornadoes in the United States over the past 60 years. The United States has about 1,000 tornadoes every year. We don't know how many tornadoes actually form each year because many of them don't touch the ground or are never reported. On average, tornadoes in the United States kill approximately 60 people each year. Many of the deaths are caused from falling or flying debris. Many times flooding plays a major role in the damage.
