By Seymour Simon
It's the earthquake version of Simon's Volcanoes: huge real photographs, short plain sentences, this time about why and how the ground itself moves.
Simon opens by explaining what an earthquake is: the giant cracked plates that make up Earth's surface grinding against each other until the rock finally gives. Then the photographs take over. They show the aftermath, not the quake itself, because no camera catches a fault slipping. Split roads, a house dropped into the street, San Francisco in 1906 and again in 1989. He covers faults, seismic waves, how a seismograph records a tremor, why quakes are so hard to predict, and what keeps a building standing when the ground won't.
If your child loved Volcanoes, this is the same book aimed at a different subject: one large photograph per spread, a few short sentences beside it, short enough to read in one sitting. The subjects don't always overlap, though. Plenty of children want lava and shrug at plate tectonics, or the other way around, so loving one book is a good sign but not a guarantee.
