This is real, cutting-edge science, written for kids. Best of all, at the end of the book, activities bring the science to life: learn how to be safer in an earthquake, experiment with earthquake-safe construction using marshmallows and jello, and even build your own seismometer!



Judith Hubbard is a geology professor with a PhD from Harvard University and a BS from Caltech - and also two young children. She started the In Depth Science series with the goal of making college-level science accessible to children as young as eight years old.

Slowly, the tectonic plates are moving. Somewhere deep beneath your feet, the rocks in the Earth are squeezing. Someday they might suddenly break and slip, sending waves of energy through the rock, shaking the ground, and knocking over buildings. Scientists and engineers work together to figure out which areas are at risk of earthquakes, to build buildings that will not fall down, and to design special warning systems. If you understand how earthquakes work, you can be prepared, too!
