ABSTRACT:
A method for detecting earthquakes comprises the steps of picking up pre-earthquake long waves or earth currents at four or more observation points located underground or at the sea bottom, carrying out a computation based on the interrelation among the so-obtained= signals to obtain the three-dimensional distribution of the sources and intensities of the long waves or earth currents, and predicting the focal region, scale and time of occurrence of earthquakes from the time-course variation in the so-obtained three-dimensional image of the wave source.
