There are obvious craters on Earth (and the moon) that show us a long history of large objects hitting the planet. But what if one hit Earth today?
Earthquakes and their resulting aftershocks can be devastatingly destructive. Earthquakes are caused when a fault in the Earth's crust slips, which releases energy waves in the ground. Find a list of 12 of the most destructive earthquakes in history.
Tornadoes are dangerous things, so it's important for you and your family to be prepared in the event of one. The United States experiences more tornadoes than the rest of the world due to low-lying geography. See our list of 15 tornado safety tips.
