Figure 3: From left to right: deepening of the anomaly trough between crests, formation of crests in predawn hours, and strong distortion of equatorial anomaly with trough movement to the north from geomagnetic equator. Vertical arrows indicate the latitudinal position of the earthquake epicenter. In the figure legends the left column of numbers indicates the time (in hours) of satellite pass over the epicenter latitude in relation to the earthquake moment. Sign − indicates time before the shock and sign + time after the shock. The right column of numbers shows the longitudinal shift of the satellite orbit ground projection in relation to the epicenter longitude.
