Humans like to think that planet Earth belongs to us. But natural disasters remind us that we're really just along for the ride. In every place humans live, the possibility of a natural disaster exists. There are wildfires in hot, dry regions and avalanches in cold, moist ones. On land, earthquakes rattle buildings and topple trees; underwater, they can trigger monster waves capable of erasing entire coastlines. Volcanoes burble up from Earth's molten core, and hurricanes, tornadoes, and lightning come from the sky. Explore these powerful forces of nature.
