Satellite Measured Ionospheric Magnetic Field Variations over Natural Hazards Sites

Processes and threats related to natural hazards play an important role in the evolution of Earth human history. The purpose this study is investigate magnetic field variations measured at low orbit (LEO) altitudes possibly associated with earthquakes, volcanic eruptions, artificial outbursts. We focus on two missions well equipped magnetometer packages, China Seismo-Electromagnetic Satellite (CSES) ESA’s three spacecraft Swarm fleet. After a survey context satellites, consideration external magnetospheric solar influences, together interferences, wavelet analysed spatio-temporal patterns ionospheric atmospheric waves are examined detail. provide assessment links between specific lithospheric or near surface sources measurements. For some diverse events achieved statistical results show change pattern pre- post-event periods, we there increase fluctuations for higher frequency (smaller scales) components. Our relevant studies which establish link space based measurements hazards.
