Milne, who spent years studying earthquakes in Japan, gives a systematic account of earth movements: sudden earthquakes, minute tremors, slow pulsations and long oscillations. He explains the instruments used to measure them, the theory and observation of earthquake motion, how to locate an earthquake’s origin, and the damage shocks do to buildings.
