The Empire State Building is designed to serve as a lightning rod for the surrounding area. It is struck by lightning about 100 times per year. During windstorms and rainstorms, the building does not sway, but it does "give". With a wind of 110 miles an hour, the building gives 1.48 inches. Movement off center is never greater than one quarter inch, thus measurable movement is only one half inch, one quarter inch on either side.
