Variations of phase velocity and gradient values of ULF geomagnetic disturbances connected with the Izu strong earthquakes
Results of study of anomaly behavior of amplitudes, phase velocities and gradients of ULF electromagnetic disturbances (<i>F</i> = 0.002 – 0.5 Hz) before and during a seismic active period are presented. Investigations were carried out in Japan (Izu and Chiba peninsulas) by two group...
