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.
The article presents the results of the analysis of TEC variations obtained from the data of receivers of global navigation satellite systems in New Zealand on the day of the earthquake on November 13, 2016. It was shown that the N-wave propagated in the north and northeast directions from the epicenter of the earthquake, while no disturbance was recorded in other azimuthal directions. The disturbance amplitude was about 0.7 TECU, and the duration was 8 minutes.
The present study focuses on the determination of the parameters of disturbance occurring in the ionosphere as a result of the impact of the jet engines of the ship "Progress". It has been shown that in the area of influence a negative disturbance is observed, as well as a negative impulse in the derivative of the TEC.
