Towards Earthquake Early Warning Systems: Insights from Satellite Data on 2023 Türkiye Earthquake

Recent studies have revealed that satellite data detected anomalies in the ionosphere up to 19 days before the devastating earthquake in Turkey on February 6, 2023, highlighting the potential for developing Earthquake Early Warning Systems. This discovery, published in the Journal of Applied Geodesy, analyzed data from the Chinese seismo-electromagnetic satellite CSES-01 and the European Space Agency’s Swarm satellites. These anomalies included changes in land surface temperature, water vapor, methane levels, ozone, carbon monoxide, and ionospheric parameters such as electron density and temperature. The research led by Professor Mehdi Akhoondzadeh from the University of Tehran highlighted that these anomalies appeared sequentially: starting from the ground, moving to the atmosphere, and finally manifesting in the ionosphere. This pattern suggests that these signals originate in the ground and propagate upward, potentially serving as precursors to seismic events.
