Abstract
The present invention describes the use of a space-based Extremely Low Frequency (ELF) magnetic field detector in conjunction with ground-based network of ELF magnetic field detectors. In particular, a space based ELF detection system can be used to perform a wide area search and find precursor earthquake signals in both known and unknown earthquake zones, and a ground-based network of ELF detectors can be used to verify that the signals are indeed earthquake generated signals. The use of this invention will minimize cost and manpower necessary to effectuate an accurate and reliable earthquake detection system.

27. A method of locating an extremely low frequency (ELF) signal comprising:
-
a) generating an ELF data signal from a satellite in response to an electromagnetic signal emanating from and characterizing an earthquake b) calculating an estimated centerpoint of said ELF signal based on data received from said satellite;
c) deploying a ground monitor at said centerpoint;
