Abstract:
The first official record of an earthquake on the Japanese island can be found in the "Chronicles of Japan," ("Nihon Shoki") in the fifth year (416) of the reign of Emperor Ingyo. However, the scientific study of earthquakes was not started until the 1880 founding of the Japan Seismological Society following the Yokohama earthquake (M=5.5) which interested three engineering professors fro Europe: John Milne (1850-1913), James A. Ewing (1855-1935), and Thomas Gray (1850-1908).
