According to data from NASA's TRMM satellite, the most lightning-struck place on Earth is Lake Maracaibo in Venezuela, averaging more than 200 flashes per square kilometre per year. Night-time storms form there very often, as warm, moist air over the lake meets winds coming down from the surrounding mountains. The near-nightly show has a name: the Catatumbo lightning.
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.
