The mission goal of QuakeSat was to determine if there were any ultra low frequency (ULF) magnetic signals, associated with large earthquakes, that could be detected using a satellite-based induction magnetometer flying in low earth orbit (LEO). QuakeSat is a small satellite, 4'x4'x12', launched on June 30, 2003, and provides a 'proof-of-concept' for collecting ULF earthquake precursor signals from space. The design was based on the CubeSat concept where ...
Since ULF magnetic anomalies were discovered prior to the 1989 Loma Prieta, Ca. M7.0 earthquake, QuakeFinder, a small R&D group based in Palo California has systematically monitored ULF magnetic signals with a network of 3-axis induction magnetometers starting in 2000. This raw magnetometer data was collected at 20-50 samples per sec. with no preprocessing, in an attempt to collect an accurate time history of electromagnetic waveforms prior to, ...
