极低频电磁信号方面，MD的公司和学生曾经发过几颗监视卫星，但这个理论的科学性受到质疑。
XXXXXXXXXXXXXXXXXXXXXXX/wiki/QuakesatQuakesat is an earth observation nanosatellite based on 3 CubeSats. It was designed to be a proof-of-concept for space-based detection of ELF signals, thought by some to be earthquake precursor signals. The science behind the concept is disputed.[1][2][3]
The students working on the project are hoping that the detection of magnetic signals may have value in showing the onset of an earthquake.[4] The company, QuakeFinder, that put the satellites together is from Palo Alto, California. They're gathering data on the extremely low magnetic field fluctuations that are associated with earthquakes to help better understand this area of study. The primary instrument is a magnetometer housed in a 2 foot (0.6 m) telescoping boom.
The 30 June 2003 deployment of Quakesat was along side other university CubeSats and one commercial CubeSat. The launch occurred on a Rockot rocket from Russia’s Plesetsk launch site.

刚看到有人发射卫星的时候以为地震预报有了转机，仔细一看还是民间行为、科学价值受质疑，说难听点就是民科。
看来“地震不可短期预报”的说法目前还没被打破。
