Like other books by Science Service, this is a good, brief, and practical overview of the subject the book is named for. In Earthquakes, the unnamed author or authors describe major earthquakes in history, the physics, side effects and correlated events like tsunamis and mudslides, how we have developed technology over the centuries to measure and predict earthquakes, and how we can mitigate damage by constructing urban areas differently.
This slim volume of scientific and historic data on earthquakes provides a good overview of the topic, though it was published in 1968 (my edition is not from 1974, as the book data above states) so more recent information is not included.
