Earthquakes

Are Caused By?

The ancient Hawaiians thought they were the angre goddess Pele stamping her feet. And people in the nineteenth century thought the earth was cooling and shrinking as it became older.

A clear and simple introduction to earthquakes: what they are, how we measure them, and what causes them. Definitely recommended for younger readers; older readers would probably prefer Asimov’s New Guide to Science or the equivalent.
