Our planet is full of scary events, phenomena, and natural disasters that change the face of Earth every day. Tornadoes, earthquakes, volcanic eruptions, hurricanes, floods, tsunamis, fires... And then, just when you think you've seen it all, nature presents you with another startling phenomenon. Rocks rolling down the slopes of a rumbling volcano, pushing other, bigger rocks on their way, and eventually tumbling down into the ocean in a humongous cascade, causing a wave the height of which the world’s never seen before. This is what might happen if the Hilina Slump of the Hawaiian Big Island falls off into the water.

Or imagine an eruption spewing tons of huge rocks and rivers of hot lava, pumping out clouds of ash that make countries stop air travel for weeks. And now multiply all this by a thousand. This is what a Yellowstone eruption would look like. Yes, Yellowstone is, first and foremost, an enormous caldera — basically, a slumbering supervolcano! And if dinosaurs could talk (and were at least still alive, for that matter), they’d tell you that asteroid threat is as real as it gets... Let's find out what naural disasters could happen any moment and affect millions.
