Air is a good electrical insulator. The primary reason why lightning has a propensity to hit the very tallest objects is because the insulating effect of air is less than is the case for structures having a shorter stature. However, it’s a mistake to think that nearby objects are relatively safe during electrical storms simply because they’re further from the base of the storm cloud. T his animation, from a storm on June 19, 2013, shows the Eiffel Tower escaping the bolts that crashed nearby. However, It shouldn’t be a surprise to learn that the 1,063 ft (324 m) high Eiffel Tower is often the target of lightning events. The strike at left shows the Tower getting hammered by a muscular discharge during an unusual morning thunderstorm on July 27, 2013. Such are the vagaries of lightning, which clearly demonstrates the need to take heed whenever thunder is heard.
