The Giant Asteroid Passed Near the Earth a Week Ago is Orbited By 2 Small Moons
Humans have witnessed many cataclysmic volcanic eruptions, from the one that destroyed Pompeii in 79 A.D. to the extraordinary Krakatoa eruption of 1883. But around the world right now there are about 20 so-called “supervolcanoes” that could outdo them all. One of these monster volcanoes lurks beneath Yellowstone National Park. The Yellowstone Caldera is an enormous craterlike depression measuring 30 miles by 45 miles and filled with molten material (magma). If it were to blast its innards out in a super-eruption, it’s no exaggeration to say that the human race could be imperiled.
