Abstract

A method of predicting an earthquake in a seismically active region below an inosphere, including the steps of measuring (10, 12) a relative fluctuation of plasma density (26) in the inosphere (20), inferring a relative amplitude of an acousto-gravity wave in the inosphere (20), and inferring an earthquake magnitude from the relative amplitude of the acousto-gravity wave.
