Resumo | Earthquakes are known to generate disturbances in the ionosphere due to the Lithosphere-Atmosphere-Ionosphere coupling in which seismic energy is transferred in the atmosphere and ionosphere in the form of Acoustic-Gravity Waves. Such disturbances, known as co-seismic ionospheric disturbances (CIDs) were previously reported for large earthquakes with magnitudes Mw ≥ 6.6. The present study reports CIDs associated with Ridgecrest earthquakes of magnitudes (Mw=6.4, 4.6), that occurred on 4 July 2019 in California, USA. The CIDs occurred as Traveling Ionospheric Disturbances (TIDs) in total electron content (TEC) data. These seismic-origin TIDs acquire unique wave characteristics that distinguish them from TIDs of non-seismic origin arising from a moderate geomagnetic activity on the same day. Their spectral characteristics relate them to the Earths normal modes and atmospheric resonance modes. The vertical ground velocity associated with the mainshock, rather than the vertical ground displacement, is found to satisfy the threshold criteria required for generation of detectable CIDs in TEC measurements. The cross-correlation analysis is used to quantify the wave parameters and their role in the identification of ∆TEC of seismic origin. Numerical simulation confirms that the Seismo-Atmosphere-Ionosphere coupled dynamics energized by the atmospheric waves is responsible for the generation of the observed CIDs. Our work demonstrates the potential of TEC measurement to detect ionospheric counterparts of moderate and weak earthquakes. We found a new vertical ground velocity threshold at 2-6 mHz of approximately 0.1-0.6 cm/s, which can generate an ionospheric drift corresponding to approximately 60-360 m/s. Therefore, these drifts are sufficient to generate CIDs detectable in TEC data series. |
