I'm surprised it's that low. In the first several weeks alone Israel dropped hundreds of 2,000lb bombs. "The heavy munitions, mostly manufactured by the US, can cause high casualty events and can have a lethal fragmentation radius – an area of exposure to injury or death around the target – of up to 365 meters (about 1,198 feet), or the equivalent of 58 soccer fields in area." That doesn't even count all the other munitions used.
