Despite the saying, lightning has no memory: it happily hits the same spots again and again, especially tall, pointed, isolated ones. New York's Empire State Building is struck about 20 to 25 times a year. A single flash often consists of several successive strokes travelling down the same channel within a fraction of a second.
On 27 August 1883, the eruption of the Indonesian volcano Krakatoa was heard as far away as Rodrigues Island, nearly 4,800 km away. Its pressure wave was picked up by barometers worldwide and circled the globe several times. The tsunamis that followed killed more than 36,000 people.
The deepest known point in the ocean, Challenger Deep, lies roughly 10,900 m below the Pacific surface. Drop Everest in and its summit would still sit about 2 km underwater. Down there, the pressure is more than 1,000 times what you feel at sea level, roughly a tonne pressing on every square centimetre.
