Special Issue Information

Dear Colleagues,

Earthquake is a severe natural disaster endangering human society, and therefore it is necessary to investigate new methods and theories for earthquake prediction. In recent years, some reports have revealed that the ionospheric plasma over the seismogenic zone has a direct relationship with the following earthquakes; the seismic waves generated by strong solid-earth processes can travel vertically to ionospheric altitude and disturb ionospheric electron densities. A comprehensive understanding of the features and physical mechanisms of the seismic–ionospheric coupling effect is important for the development of real-time earthquake early warning systems based on space-geodetic techniques. With the rapid development of cutting-edge multi-GNSS systems and low-orbit radio occultation systems (COSMIC-1/2, FY-3C/D, etc.), GNSS remote sensing techniques offer an unprecedented opportunity for ionospheric modeling, and provide high-accuracy geodetic data for space weather monitoring and other associated applications. To take advantage of advanced GNSS remote sensing techniques, this Special Issue aims to present new studies that address topics including but not limited to:

  • Advanced methods for detecting seismic–ionospheric signals.
  • Ionospheric monitoring during severe space events.
  • Deep learning techniques in earth system models.
  • Seismic–ionospheric coupling mechanisms.
  • Applications of ionospheric anomaly to monitoring natural disasters.
  • Ionosphere modelling.
  • GNSS data processing for TEC.
  • Case studies of seismic–ionospheric effects.

The Tonga volcano erupted on 15 January 2022, at 04:15:45 UTC, which significantly influenced the atmosphere and space environment, at the same time, an unprecedented opportunity to monitor ionospheric anomalies is provided by its powerful eruption. In current studies of traveling ionospheric disturbance (TID) triggered by the 2022 Tonga volcanic eruption, the particular phenomenon of ionospheric disturbances in various parts of the world has not been reasonably explained, and the vertical ionospheric disturbances are still not effectively detected. In this paper, we calculate the high-precision slant total electron content (STEC) from more than 3000 ground-based GPS stations distributed around the world, then we obtain the radio occultation (RO) data from near-field COSMIC-2 profiles and investigate the horizontal TID and the vertical ionospheric disturbances by the singular spectrum analysis (SSA). Horizontal TID propagation captured by GPS STEC results indicates that acoustic-gravity waves dominate the energy input at the beginning of the ionospheric disturbance with an approximate speed of 1050 m/s initially. With the dissipation of the shock energy, lamb waves become a dominant mode of ionospheric disturbances, moving at a more stable speed of about 326 m/s to a range of 16,000 km beyond the far-field. Local characteristics are evident during the disturbance, such as the ionospheric conjugation in Australia and the rapid decay of TID in Europe. The shock-Lamb-tsunami waves’ multi-fluctuation coupling is recorded successively from the COSMIC-2 RO observation data. The shock and Lamb waves can perturb the whole ionospheric altitude. In contrast, the disturbance caused by tsunami waves is much smaller than that of acoustic-gravity waves and Lamb waves. In addition, influenced by the magnetic field, the propagation speed of TID induced by Lamb waves is higher towards the northern hemisphere than towards the southern hemisphere. Full article
