The full extent of the destruction caused by the enormous tornado that ripped through Oklahoma was still being determined as night fell on Monday. At least 51 people were killed, including seven children at an elementary school. Entire blocks of homes were flattened. At one hospital alone 85 patients, including 65 children, were being treated for injuries. And many were still missing. Here's a look at how Monday's horrific storm compares to some of the deadliest tornadoes in U.S. history:

Peak winds, roaring over 200 miles per hour, destroyed the Missouri town, killing 162 people and causing an estimated $2.8 billion in damage, according to the National Weather Service. The Weather Channel's severe weather expert Greg Forbes estimates more than 17,000 people were affected. Nearly two years later, the town is still rebuilding.

The F4 tornado killed 65 during a record-setting day when 200 twisters spun through the Southeast. The spring and summer of 2011 was one of the most active, deadly and destructive periods of tornado activity in U.S. history. That year there were a reported 551 fatalities and $28 billion in damages, according to the Almanac.
