China launches new seismo-electromagnetic satellite with European partners
China launches new seismo-electromagnetic satellite with European partners China launched a second collaborative seismo-electromagnetic satellite early Saturday, aimed at detecting electromagnetic precursors to natural disasters such as earthquakes.
CSES-2 aims to enhance China’s early warning and risk assessment capabilities, and monitoring of natural disasters such as earthquakes, tsunamis, volcanic eruptions and severe storms. The CSES-1 satellite detected significant changes in electric and magnetic field oscillations, plasma density and energetic particles that correlate with seismic activity and thunderstorms, according to a paper published in the journal Earthquake Research Advances in January. Its observations also include potential precursory signals to earthquakes and volcanic activity, such as ionospheric disturbances and plasma anomalies, suggesting that space-based electromagnetic monitoring can support early warning systems.
