上个世纪以来，与地震（EQ）活动相关的异常电磁（EM）发射被地面和卫星观测广泛报道和记录。地震辐射极低频（ELF）电磁波的机制已逐渐建立。然而，低地球轨道（LEO）卫星能否探测到地震辐射电磁波仍存在争议。针对这些问题，本文提出了一种ELF波岩石圈-大气-电离层模型。研究了低地轨道卫星高度的地震辐射模拟电磁场特征，并将中国地震电磁卫星（CSES）高度的模拟电磁场与CSES星载电磁传感器的灵敏度进行了比较。结果表明，CSES电磁传感器可以探测到6.0级以上的地震，但这取决于震源深度、孕震环境和电离层参数。
Over the last century,abnormal electromagnetic(EM)emissions associated with earthquake(EQ)activities have been widely reported and recorded by ground-based and satellite observations.The mechanism of extremely low-frequency(ELF)EM waves radiated from earthquakes has been gradually established.However,whether EM waves radiated from earthquakes can be detected by low Earth orbit(LEO)satellites remains controversial.In this paper,to address these concerns,a lithosphereatmosphere-ionosphere model of ELF wave propagation is constructed.The features of the simulated EM field at LEO satellite altitudes radiated from earthquakes have been studied.The simulated EM field at the altitude of the China Seismo-Electromagnetic Satellite(CSES)is compared with the sensitivity of electromagnetic(EM)sensors onboard the CSES.The results illustrate that an earthquake with a magnitude over 6.0 can be detected by the EM sensors of the CSES.However,this depends on the focal depth,seismogenic environment and ionospheric parameters.
