Earthquakes: Nothing shakes up our planet quite like an earthquake can. Earthquakes can rattle the ground from left to right, front to back, or even up and down. Most are too light to be felt. The rare, powerful earthquakes are the ones that people don't forget. In this book, you'll get a groundbreaking look at earthquakes: how and why they happen, what damage they cause, and what to do if "the big one" strikes!
