Gr 2-4-- A look at the dynamics of quakes, early detection systems, and measures taken by architects and city planners to lessen dangers after an earthquake occurs. Branley's explanations are in terms that children will easily understand, and the information is compressed into child-size bites, especially when describing earthquake motions. Branley may be too concise, however, when he fails to state the connection between seismic waves and readings on the Richter scale. Only an adult will be able to deduce what is only implied in the text rather than spelled out. A readable book with brightly colored illustrations that are serviceable but not particularly inspired. --Gloria Amann, New York Public Library
