Abstract

Numerous articles (for example, [1-2]) on the registration of ionospheric responses to various events indicate the effectiveness of the use of GNSS receiver networks for these purposes. On November 13, 2016, several earthquakes were recorded in New Zealand. The magnitude of the main shock was 7.8 [3]. From the analysis of the GNSS measurement data, it was found that 10 minutes after the shock, the ionospheric reaction began. After another 3 minutes, a wave front of N-wave disturbance with a maximum amplitude of ~ 0.7 TECU is clearly distinguished. There is a pronounced anisotropy of disturbance registration in the northeast - southwest direction. Thus, no disturbance was registered in the southwest direction. This effect is probably related to the influence of the Earth's magnetic field.
