Could Electron Counts Detect Major Earthquakes?

hcs_$reboot writes "According to a Japanese researcher, the electron count escalation high in the atmosphere could indicate that a major earthquake is going to happen within 30~40 minutes. That phenomenon was observed before three earthquakes since 2004. If confirmed, the earthquake detection system could save thousands of lives."

TFA says:

There is a dense network of GPS satellites, especially over earthquake-prone areas like Japan,

Is GPS satellite distribution not uniform-on-average across the globe? Sombody can 'splains?

Anyone know EM wave physics well? Would the published levels of changing ionospheric charge modify the Schumann resonance enough to allow for remote (global?) detection by watching the ~7Hz wavebands?
