Seismo-magnetic Effect and the Possibility of Forecasting Earthquakes

Abstract

THE existence of a correlation between magnetic disturbances and seismic activity has been suspected for nearly a century; but so many of the early observations were due solely to the mechanical vibration of magnetometers by seismic waves that when Lapina1 reviewed the subject in 1953 she concluded that no effect had been satisfactorily demonstrated. However, sufficient evidence had been accumulating in Japanese literature to justify a renewed examination of the problem.
